What does God say when man approves sin?
Because with lies ye have made the heart of the righteous sad, whom I have not made sad; and strengthened the hands of the wicked, that he should not return from his wicked way, by promising him life: (Ezekiel 13:22)
I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness: they are all of them unto me as Sodom, and the inhabitants thereof as Gomorrah. (Jeremiah 23:14)
Approval and acceptance of sin only brings more sin, evil, and death upon mankind. Acceptance only strengthens the resolve of evildoers to commit more evil.
