Bible Verses About Alliance and Society with the Enemies of God: Are ruinous to spiritual interest

Whoever is an accomplice of a thief is an enemy of his own soul. He takes an oath, but dares not testify.

Follow after peace with all men, and the sanctification without which no man will see the Lord,

looking carefully lest there be any man who falls short of the grace of God; lest any root of bitterness springing up trouble you, and many be defiled by it;

You therefore, beloved, knowing these things beforehand, beware, lest being carried away with the error of the wicked, you fall from your own steadfastness.
