“For this reason we also constantly thank God that when you received the word of God which you heard from us, you accepted it not as the word of men, but for what it really is, the word of God, which also performs its work in you who believe” (1 Thessalonians 2:13, NASB).
The Apostle Paul praised the Thessalonians for accepting his preaching as if it was words spoken by God. The words he spoke to them weren’t just impotent words spoken by human beings but the very Word of God.
