13For this reason we also thank God #Rom. 1:8; 1 Thess. 1:2, 3without ceasing, because when you #Mark 4:20received the word of God which you heard from us, you welcomed it#(Matt. 10:20; Gal. 4:14)not as the word of men, but as it is in truth, the word of God, which also effectively #(1 Pet. 1:23)works in you who believe.
