3 We know that we have come to know him if we keep his commands. 4 Whoever says, "I know him," but does not do what he commands is a liar, and the truth is not in that person. 5 But if anyone obeys his word, love for God[1] is truly made complete in them. This is how we know we are in him: 6 Whoever claims to live in him must live as Jesus did.

7 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. 8 Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining. 9 Anyone who claims to be in the light but hates a brother or sister[2] is still in the darkness. 10 Anyone who loves their brother and sister[3] lives in the light, and there is nothing in them to make them stumble. 11 But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.

3 And hereby we do know that we know him, if we keep his commandments. 4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him. 5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him. 6 He that saith he abideth in him ought himself also so to walk, even as he walked.

7 Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning. 8 Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth. 9 He that saith he is in the light, and hateth his brother, is in darkness even until now. 10 He that loveth his brother abideth in the light, and there is none occasion of stumbling in him. 11 But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.

The Message

Tests of True Knowledge

3 Here's how we can be sure that we know God in the right way: Keep his commandments. 4 If someone claims, "I know him well!" but doesn't keep his commandments, he's obviously a liar. His life doesn't match his words. 5 But the one who keeps God's word is the person in whom we see God's mature love. This is the only way to be sure we're in God. 6 Anyone who claims to be intimate with God ought to live the same kind of life Jesus lived.

7 My dear friends, I'm not writing anything new here. This is the oldest commandment in the book, and you've known it from day one. It's always been implicit in the Message you've heard. 8 On the other hand, perhaps it is new, freshly minted as it is in both Christ and you - the darkness on its way out and the True Light already blazing! 9 Anyone who claims to live in God's light and hates a brother or sister is still in the dark. 10 It's the person who loves brother and sister who dwells in God's light and doesn't block the light from others. 11 But whoever hates is still in the dark, stumbles around in the dark, doesn't know which end is up, blinded by the darkness.

New King James Version

3 Now by this we know that we know Him, if we keep His commandments. 4 He who says, "I know Him," and does not keep His commandments, is a liar, and the truth is not in him. 5 But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him. 6 He who says he abides in Him ought himself also to walk just as He walked.

7 Brethren, NU-Text omits from the beginning. I write no new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word which you heard from the beginning. 8 Again, a new commandment I write to you, which thing is true in Him and in you, because the darkness is passing away, and the true light is already shining. 9 He who says he is in the light, and hates his brother, is in darkness until now. 10 He who loves his brother abides in the light, and there is no cause for stumbling in him. 11 But he who hates his brother is in darkness and walks in darkness, and does not know where he is going, because the darkness has blinded his eyes.

New Living Translation

Tests of True Knowledge

3 And we can be sure that we know him if we obey his commandments. 4 If someone claims, "I know God," but doesn't obey God's commandments, that person is a liar and is not living in the truth. 5 But those who obey God's word truly show how completely they love him. That is how we know we are living in him. 6 Those who say they live in God should live their lives as Jesus did.

7 Dear friends, I am not writing a new commandment for you; rather it is an old one you have had from the very beginning. This old commandment-to love one another-is the same message you heard before. 8 Yet it is also new. Jesus lived the truth of this commandment, and you also are living it. For the darkness is disappearing, and the true light is already shining. 9 If anyone claims, "I am living in the light," but hates a fellow believer, that person is still living in darkness. 10 Anyone who loves a fellow believer is living in the light and does not cause others to stumble. 11 But anyone who hates a fellow believer is still living and walking in darkness. Such a person does not know the way to go, having been blinded by the darkness.

Matthew Henry's Commentary on 1 John 2:3-11

Commentary on 1 John 2:3-11

(Read 1 John 2:3-11)

What knowledge of Christ can that be, which sees not that he is most worthy of our entire obedience? And a disobedient life shows there is neither religion nor honesty in the professor. The love of God is perfected in him that keeps his commandments. God's grace in him attains its true mark, and produces its sovereign effect as far as may be in this world, and this is man's regeneration; though never absolutely perfect here. Yet this observing Christ's commands, has holiness and excellency which, if universal, would make the earth resemble heaven itself. The command to love one another had been in force from the beginning of the world; but it might be called a new command as given to Christians. It was new in them, as their situation was new in respect of its motives, rules, and obligations. And those who walk in hatred and enmity to believers, remain in a dark state. Christian love teaches us to value our brother's soul, and to dread every thing hurtful to his purity and peace. Where spiritual darkness dwells, in mind, the judgment, and the conscience will be darkened, and will mistake the way to heavenly life. These things demand serious self-examination; and earnest prayer, that God would show us what we are, and whither we are going.
