1 St John 3:11-20

For this is the declaration, which you have heard from the beginning, that you should love one another. Not as Cain, who was of the wicked one, and killed his brother. And wherefore did he kill him? Because his own works were wicked: and his brother's just. Wonder not, brethren, if the world hate you. We know that we have passed from death to life, because we love the brethren. He that loveth not, abideth in death. Whosoever hateth his brother is a murderer. And you know that no murderer hath eternal life abiding in himself. In this we have known the charity of God, because he hath laid down his life for us: and we ought to lay down our lives for the brethren. He that hath the substance of this world, and shall see his brother in need, and shall shut up his bowels from him: how doth the charity of God abide in him? My little children, let us not love in word, nor in tongue, but in deed, and in truth. In this we know that we are of the truth: and in his sight shall persuade our hearts. For if our heart reprehend us, God is greater than our heart, and knoweth all things.
