1 John 3 [16.] By this we know love, because he laid down his life for us. And we ought to lay down our lives for the brothers. But whoever has the world’s goods, and sees his brother in need, and closes his heart of compassion against him, how does the love of God remain in him? My little children, let’s not love in word only, or with the tongue only, but in deed and truth. And by this we know that we are of the truth, and persuade our hearts before him, because if our heart condemns us, God is greater than our heart, and knows all things.
1 John 3 [21.] Beloved, if our hearts don’t condemn us, we have boldness toward God; and whatever we ask, we receive from him, because we keep his commandments and do the things that are pleasing in his sight. This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded. He who keeps his commandments remains in him, and he in him. By this we know that he remains in us, by the Spirit which he gave us.
1 John 4 [1.] Beloved, don’t believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world. By this you know the Spirit of God: every spirit who confesses that Jesus Christ has come in the flesh is of God, and every spirit who doesn’t confess that Jesus Christ has come in the flesh is not of God, and this is the spirit of the Antichrist, of whom you have heard that it comes. Now it is in the world already. You are of God, little children, and have overcome them; because greater is he who is in you than he who is in the world. They are of the world. Therefore they speak of the world, and the world hears them. We are of God. He who knows God listens to us. He who is not of God doesn’t listen to us. By this we know the spirit of truth, and the spirit of error.
