but a test everything; hold fast what is good.
Abstain from every form of evil.

1 John 4:1
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.
Let us choose what is right; let us know among ourselves what is good.
And try to discern what is pleasing to the Lord.
