3:23 And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
3:24 And he that keepeth his commandments dwelleth in him, and he in him.
And hereby we know that he abideth in us, by the Spirit which he hath given us.
4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
4:2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: 4:3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
4:4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
4:5 They are of the world: therefore speak they of the world, and the world heareth them.
4:6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
4:7 Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
4:8 He that loveth not knoweth not God; for God is love.
