1 John 4:1-3, 7, 15

Beloved, believe not every spirit, but prove the spirits, whether they are of God; because many false prophets are gone out into the world. Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God: and every spirit that confesseth not Jesus is not of God: and this is the spirit of the antichrist, whereof ye have heard that it cometh; and now it is in the world already.

Beloved, let us love one another: for love is of God; and every one that loveth is begotten of God, and knoweth God.

Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God.
