How you can KNOW
you are a Christian or not

1st John 2:3-5

3 And hereby we do know that we know him, if we keep his commandments.

By this we know now, in the present, that we have come to know him, in the past, with the evidence that we know Him now, in the present, if, we are presently keeping His commandments.

Now this verse and the breakdown of the verbs in the verse, makes for some rather earth shattering implications on the professing Christian Church today that we all better take heed to. Since what John said was, and is, the absolute truth, then we had better examine the verse in the light of what is said, rather than an opinion or some experience on our part. John states with absolute knowledge and an unchanging certainty that our so-called conversion experience in the past is only valid if conversion is demonstrated in the present. Our so-called profession of being saved in the past is only valid if there are PRESENT evidences of it being demonstrated in the life of the one professing to be a believer. This means in all simplicity that if you point to a time or a place or some experience in the distant past as a means to justify your professed Christianity, yet, in the present, you have no evidence that the conversion is genuine, your experience in the past is also invalid. This is exactly what John is saying in this verse and what he said is absolute and true today. The sole evidence that John gives for the reality of any genuine conversion, past or present, is the believers relationship to the commandments that Christ gave to His followers. You can know and do know right now, right this second, that you are truly a believer or not. You can know this second whether the experience or the professed "coming to the Lord" in your past, was genuine or counterfeit or not, by the present test of obedience to the commandments of Christ. This statement on the part of John is absolute and unchanging, no matter how the tide of the church changes, God's word on this issue is unchanging and that is it. An individual's response to this bible is the central key to whether a profession is real or counterfeit or not. There is no mystery, no guesswork and no other discussion needs to be made concerning the issue. God has already spoken about it and we need to say what He said about it. If you today cannot see evidences in your life of present obedience to the word of God, of the keeping of the commandments of Christ as a habit of your life, of obedience to the scriptures, then you are not a believer, God is not your Heavenly Father, you are not saved, you are not going anywhere near Heaven, but are in fact a child of the devil and are altogether in the darkness. The genuine believer is careful to observe the commandments given to him or her by Christ because it is the sole act that is clearly stated that a believer truly loves the Savior or not. If a person's so-called salvation experience was real in the past, it will be real in the present and it will be real in the future.

This is the description of the perfect tense that John uses in the second verb, we know, in this verse, and that salvation will be evident by one's relationship to the word of God. End of discussion.

There are a many passages in the scriptures to support this clear teaching with many from Jesus own lips. For example:


John 14:15
15 If you love Me, you will keep My commandments.

John 14:21-23
21 He who has My commandments and keeps them, he it is who loves Me; and he who loves Me shall be loved by My Father, and I will love him, and will disclose Myself to him."
22 Judas (not Iscariot) said to Him, "Lord, what then has happened that You are going to disclose Yourself to us, and not to the world?"
23 Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him, and make Our abode with him.

John 15:10,14
10 "If you keep My commandments, you will abide in My love; just as I have kept My Father's commandments, and abide in His love.
14 "You are My friends, if you do what I command you.


John also throughout his letters makes it clear that it is characteristic of genuine believers that they walk as a habit of life in the truth.


1st John 1:6
6 If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth;

1st John 3:18-19
18 Little children, let us not love with word or with tongue, but in deed and truth.
19 We shall know by this that we are of the truth, and shall assure our heart before Him,

2nd John 1:4-6
4 I was very glad to find some of your children walking in truth, just as we have received commandment to do from the Father.
5 And now I ask you, lady, not as writing to you a new commandment, but the one which we have had from the beginning, that we love one another.
6 And this is love, that we walk according to His commandments. This is the commandment, just as you have heard from the beginning, that you should walk in it.

3rd John 1:1-4
1 The elder to the beloved Gaius, whom I love in truth.
2 Beloved, I pray that in all respects you may prosper and be in good health, just as your soul prospers.
3 For I was very glad when brethren came and bore witness to your truth, that is, how you are walking in truth.
4 I have no greater joy than this, to hear of my children walking in the truth.

Others have stated the same truth.

1st Kings 3:6
6 Then Solomon said, "Thou hast shown great lovingkindness to Thy servant David my father, according as he walked before Thee in truth and righteousness and uprightness of heart toward Thee; and Thou hast reserved for him this great lovingkindness, that Thou hast given him a son to sit on his throne, as it is this day.

Psalm 26:1-3
1 Vindicate me, O LORD, for I have walked in my integrity; and I have trusted in the LORD without wavering.
2 Examine me, O LORD, and try me; test my mind and my heart.
3 For Thy lovingkindness is before my eyes, and I have walked in Thy truth.

Psalm 86:11
11 Teach me Thy way, O LORD; I will walk in Thy truth; Unite my heart to fear Thy name.

Isaiah 38:2-3
2 Then Hezekiah turned his face to the wall, and prayed to the LORD,
3 and said, "Remember now, O LORD, I beseech Thee, how I have walked before Thee in truth and with a whole heart, and have done what is good in Thy sight." And Hezekiah wept bitterly.

Galatians 2:11-14
11 But when Cephas came to Antioch, I opposed him to his face, because he stood condemned.
12 For prior to the coming of certain men from James, he used to eat with the Gentiles; but when they came, he began to withdraw and hold himself aloof, fearing the party of the circumcision.
13 And the rest of the Jews joined him in hypocrisy, with the result that even Barnabas was carried away by their hypocrisy.
14 But when I saw that they were not straightforward (walking) about the truth of the gospel, I said to Cephas in the presence of all, "If you, being a Jew, live like the Gentiles and not like the Jews, how is it that you compel the Gentiles to live like Jews?

Go back to 1st John 2.

4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.

Here is the comparison between those who say they are Christians and those who truly are. You are not a Christian because you say you are a Christian, you are a Christian because the evidence of it is manifest in your lifestyle. Now, John speaks of the professor of faith. He or she, is known by their constant affirmation to others or to themselves that they truly have come to the reality that they know Christ, that they absolutely know that they are in a relationship with Christ through salvation, this is what they say and this is what they tell others. The truth is, whatever they say is strictly from their mouth and that's as far as it goes. They profess their allegiance to Christ and that there is an ongoing relationship with Him. Yet, the true and sole evidence that God clearly states by His own word that a person has a relationship with Him, that is, an ongoing obedience to the truth as a habit of life, is absent in the professor of faith. Rather than being a child of God, as they have affirmed to themselves and to others, God says, without hesitation and without question, that this person is a liar, a deceiver, one who speaks lies out of their mouth, they speak deliberate falsehoods. Look back at John 14:24.

John 14:24
He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.

Luke 6:46
46 And why call ye me, Lord, Lord, and do not the things which I say?

(Why are you calling Me, in the present, Master, Master, and you are not doing, in the present what I have commanded you to do?)

What difference does it make for you to keep calling Me Lord? What relevance is it to you or of what value is it for you to tell others that I am the Lord, and that I am your Lord while at the same time, disobeying what I command you to do? What difference does that make to you, Why are you doing this and for what reason? Do you think that by CALLING Me Lord, Lord, that this means that you will escape eternal judgment? Turn back to Matthew 7:21-23.

Matthew 7:21-23
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Professing to know God or to walk in the fellowship or to be a believer in Christ or to be a Christian or to be saved, EVEN with apparent good works that could be labeled, "works of God" are meaningless if we do not as a habit of life obey His word.

Go back to 1st John 2

5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.

The person who keeps His word, in the present, in that person truly the Love of God has been made complete. Again, John uses the perfect tense signifying an action that is viewed as having been completed in the past, once and for all, not needing to be repeated. In simpler terms, the person who is keeping His word is one who is saved and their past experience or confession of salvation was genuine as well. By this one thing, keeping His word, we have become acquainted with Him on a personal level. Everything rises and falls by our relationship to the scriptures. A person who loves the Lord is a genuine believer, and as a genuine believer, he or she strives to know the word, and to keep the word.

Psalm 119:2-4
2 Blessed [are] they that keep his testimonies, [and that] seek him with the whole heart.
3 They also do no iniquity: they walk in his ways.
4 Thou hast commanded [us] to keep thy precepts diligently.

Luke 11:27-28
27 And it came to pass, as he spake these things, a certain woman of the company lifted up her voice, and said unto him, Blessed [is] the womb that bare thee, and the paps which thou hast sucked.
28 But he said, Yea rather, blessed [are] they that hear the word of God, and keep it.

1st Peter 1:22-23
22 Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, [see that ye] love one another with a pure heart fervently:
23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.

Go back to 1st John 2

6 He that saith he abideth in him ought himself also so to walk, even as he walked.

Genuine salvation is also seen as abiding in Christ. This expression, abide in Him, describes a very close and intimate relationship. It is a walk of life that mirrors the life of Christ Himself. Abiding in Christ means that we go beyond a desire to want to be like Him, into behavior that imitates Him. Salvation is not to get Jesus to do for you what you want Him to do, it is to live and to walk as He walked, implying complete submission to His will. It is nothing short of total and complete dependency upon Christ. The same expression, abide in Him, is used in John's gospel, chapter 15:4-5. John uses this expression many times in this epistle also. We will see that as we proceed throughout the study of this epistle. Clearly the pattern and example is given for the believer's life and that pattern is walking, as a habit of daily life, as He walked. Now it doesn’t take an engineer to figure out what this means. It means that you and I will conduct our life after His. Whatever the scriptures reveal of the walk of Christ Jesus on Earth is to be our pattern here on Earth. It's that simple.

  • John 6:63-66: Walking as He walked means that one will walk WITH Jesus, even though these false followers did not.

  • John 8:12, 11:9-10: Walking as He walked means to FOLLOW after Him as you walk in the light and not in the darkness.

  • Romans 6:4: Walking as He walked means that you walk in newness of life. The new life that salvation produces.

  • Romans 8:1,4,14: Walking as He walked means that I walk in the Holy Spirit.

  • Ephesians 4:17-32: Walking as He walked means you stop living like the unsaved.

  • Ephesians 5:1-2: Walking as He walked means that you are an imitator of God who walks in the love of Christ.

  • Colossians 1:9-10: Walking as He walked means that you live a life that pleases God.

Colossians 2:6-7: Walking as He walked means that we will walk by faith in all of the provisions that He gave us at the moment of salvation, growing to a place of spiritual maturity.


The life of the believer began by faith in Christ Jesus. All the provisions that were needed to live the Christian life came right along with salvation. To appropriate the provisions we need to understand that they all come by faith and through Christ Jesus. The thought that somehow our spiritual life is left to ourselves to operate and that Jesus is not a willing and an active participant in our walk is ludicrous. In fact, without Him, there is no Christian life in which to speak of. We have salvation through Him, we have the provisions to live the Christian life through Him. The work of God's grace in our lives does not cease until we get to glory.

We are instructed by Paul to:

      1. Grow up in all things, Ephesians 4:15.

We are instructed by Peter to:

      1. Grow in the word, 1st Peter 2:2
      2. Grow in grace and in our daily walk with Jesus Christ, 2nd Peter 3:18

Paul said as the Colossians received Christ Jesus, the Lord, and that was by faith, so walk with our lives in union with Him in the same way, by faith. Look carefully at Colossians chapter 2 verse 7.

There are four character traits which reveal the manner in which we are to walk by faith, in Christ. The first is:

1) Rooted: This participle is translated, having been rooted. This is our initial of being connected with Jesus through salvation. This same word is found in Ephesians 3:14-19. Paul's desire is that the rooted believer continues to grow to full spiritual maturity.

2) Built up in Him: Being built up. Whereas, being rooted was a past completed action, being built up is a continuous, present action of the life of the believer. This word speaks of constructing a house. Christ is not finished with you and I, there is much work that needs to be done.

3) Stablished in the faith: Being strengthened in the embodiment of truth. We need to be fixed firmly on the foundation of biblical truth. We need to be fixed firmly on the foundation of biblical truth. We need to be fixed firmly on the foundation of the person and work of Jesus Christ. Notice the words: as you have been taught. The truth taught to you concerning Jesus Christ, in the past, is not to be forgotten, but is to be applied in the present.

4) Abounding in it (truth) with thanksgiving: Overflowing with thanksgiving, above any measure in gratitude to God for this great work of salvation. Giving God unceasing glory for His great work. A person's understanding of who Christ is and of what God has provided in salvation is a complete and total defense against all false teachings.
