11 For this is the message which you have heard from the beginning, that we should love one another; 12 not as Cain, who was of the evil one and slew his brother. And for what reason did he slay him? Because his deeds were evil, and his brother’s were righteous. 13 Do not be surprised, brethren, if the world hates you. 14 We know that we have passed out of death into life, because we love the brethren. He who does not love abides in death. 15 Everyone who hates his brother is a murderer; and you know that no murderer has eternal life abiding in him.
16 We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren. 17 But whoever has the world’s goods, and sees his brother in need and closes his heart against him, how does the love of God abide in him?
18 Little children, let us not love with word or with tongue, but in deed and truth. 19 We will know by this that we are of the truth, and will assure our heart before Him 20 in whatever our heart condemns us; for God is greater than our heart and knows all things.
21 Beloved, if our heart does not condemn us, we have confidence before God; 22 and whatever we ask we receive from Him, because we keep His commandments and do the things that are pleasing in His sight. 23 This is His commandment, that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded us. 24 The one who keeps His commandments abides in Him, and He in him. We know by this that He abides in us, by the Spirit whom He has given us.
