1 John 3 International Standard Version (ISV)
We are God’s Children
3 See what kind of love the Father has given us: We are called God’s children—and that is what we are![a] For this reason the world does not recognize us, because it did not recognize him, either.
2 Dear friends, we are now God’s children, but what we will be like has not been revealed yet. We know that when the Messiah[b] is revealed, we will be like him, because we will see him as he is. 3 And everyone who has this hope based on him keeps himself pure, just as the Messiah[c] is pure. 4 Everyone who keeps living in sin also practices disobedience. In fact, sin is disobedience. 5 You know that the Messiah[d] was revealed to take away sins,[e] and there is not any sin in him. 6 No one who remains in union with him keeps on sinning. The one who keeps on sinning hasn’t seen him or known him.
7 Little children, don’t let anyone deceive you. The person who practices righteousness is righteous, just as the Messiah[f] is righteous. 8 The person who practices sin belongs to the evil one, because the Devil has been sinning from the beginning. The reason that the Son of God was revealed was to destroy what the Devil has been doing. 9 No one who has been born from God practices sin, because God’s[g] seed abides in him. Indeed, he cannot go on sinning, because he has been born from God. 10 This is how God’s children and the Devil’s children are distinguished.[h] No person who fails to practice righteousness and to love his brother is from God.
Love One Another
11 This is the message that you have heard from the beginning: We should love one another. 12 Do not be like Cain,[i] who was from the evil one and murdered his brother. And why did he murder him? Because what he was doing was evil and his brother’s actions[j] were righteous. 13 So do not be surprised, brothers, if the world hates you.
14 We know that we have passed from death to life, because we love one another. The person who does not love[k] remains spiritually[l] dead. 15 Everyone who hates his brother is a murderer, and you know that no murderer has eternal life present in him. 16 This is how we have come to know love: the Messiah[m] gave his life for us. We, too, ought to give our lives for our brothers. 17 Whoever has earthly possessions and notices a brother in need and yet withholds his compassion from him, how can the love of God be present in him? 18 Little children, we must stop expressing love merely by our words and manner of speech; we must love[n] also in action[o] and in truth. 19 This is how we will know that we belong to the truth and how we will be able to keep ourselves[p] strong in his presence.
20 If our hearts condemn us, God is greater than our hearts and knows everything. 21 Dear friends, if our hearts do not condemn us, we have confidence in the presence of God. 22 Whatever we request we receive from him, because we keep his commandments and do what pleases him. 23 And this is his commandment: to believe in the name of his Son, Jesus the Messiah,[q] and to love one another as he commanded us. 24 The person who keeps his commandments abides in God,[r] and God abides in him.[s] This is how we can be sure that he remains in us: he has given us his Spirit.
1 John 3 New International Version (NIV)
3 See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him. 2 Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears,[a] we shall be like him, for we shall see him as he is. 3 All who have this hope in him purify themselves, just as he is pure.
4 Everyone who sins breaks the law; in fact, sin is lawlessness. 5 But you know that he appeared so that he might take away our sins. And in him is no sin. 6 No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
7 Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8 The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. 9 No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God. 10 This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.
More on Love and Hatred
11 For this is the message you heard from the beginning: We should love one another. 12 Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous. 13 Do not be surprised, my brothers and sisters,[b] if the world hates you. 14 We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. 15 Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
16 This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters. 17 If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? 18 Dear children, let us not love with words or speech but with actions and in truth.
19 This is how we know that we belong to the truth and how we set our hearts at rest in his presence: 20 If our hearts condemn us, we know that God is greater than our hearts, and he knows everything. 21 Dear friends, if our hearts do not condemn us, we have confidence before God 22 and receive from him anything we ask, because we keep his commands and do what pleases him. 23 And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. 24 The one who keeps God’s commands lives in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
