And we also thank God continually for this, that when you received the word of God [concerning salvation] which you heard from us, you welcomed it not as the word of [mere] men, but as it truly is, the word of God, which is effectually at work in you who believe [exercising its inherent, supernatural power in those of faith].

1 Thessalonians 3:5
