1 Thessalonians 2:10-13

10You are witnesses, and so is God, of how holy, righteous, and blameless our conduct was among you who believed. 11For you know that we treated each of you as a father treats his own children— 12encouraging you, comforting you, and urging you to walk in a manner worthy of God, who calls you into His own kingdom and glory.

13And we continually thank God because, when you received the word of God that you heard from us, you accepted it not as the word of men, but as it truly is, the word of God, which is also now at work in you who believe.
