Anyone who does what is good is from God.
Anyone who does what is evil has not seen God.
3 John 1:11 (NIV) The Righteous One knows what is going on
in the homes of the wicked;
he will bring disaster on them.
Proverbs 21:12 (NLT)
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. 1 John 4:1 (ESV)
