1 Thessalonians 2:10-13

10You are witnesses, and God also, how devoutly and justly and blamelessly we behaved ourselves among you who believe;

11as you know how we exhorted, and comforted, and charged every one of you, as a father does his own children,

12that you would walk worthy of God who calls you into His own kingdom and glory.

13For this reason we also thank God without ceasing, because when you received the word of God which you heard from us, you welcomed it not as the word of men, but as it is in truth, the word of God, which also effectively works in you who believe.
