NET

13 And so we too constantly thank God that when you received God’s message that you heard from us, you accepted it not as a human message, but as it truly is, God’s message, which is at work among you who believe.

Darby

13 And for this cause we also give thanks to God unceasingly that, having received [the] word of [the] report of God by us, ye accepted, not men's word, but, even as it is truly, God's word, which also works in you who believe.

KJV

13 For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received [it] not [as] the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
