1 John 4:1-12 KJV

Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. [2] Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: [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] 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. [5] They are of the world: therefore speak they of the world, and the world heareth them. [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. [7] Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. [8] He that loveth not knoweth not God; for God is love. [9] In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. [10] Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. [11] Beloved, if God so loved us, we ought also to love one another. [12] No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.
