1 John 2:19; 1 John 3:13; 1 John 4:1; 1 John 4:11; 1 John 5:9
They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
Marvel not, my brethren, if the world hate you.
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Beloved, if God so loved us, we ought also to love one another.
If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.
