1 Thessalonians 4:2

"Finally then, brethren, we beseech and exhort you in the Lord Jesus, that, as ye received of us how ye ought to walk and to please God, so ye abound more and more. For ye know what charge we gave you through the Lord Jesus Christ." When he has met what was pressing, and what was upon his hands, and is about henceforth to enter upon things that are perpetual, and which they ought continually to hear, he adds this expression, "finally," that is, always and forever. "We beseech and exhort you in the Lord." Strange! He does not even speak of himself as of sufficient credit to exhort. And yet who was so worthy of credit? But he takes Christ along with him. We exhort you, he says, by God. Which also he said to the Corinthians, "God entreats (exhorts) you through us." (2 Cor. v. 20) "That as ye received of us." This "received" is not of words only, but of actions also, viz. "how ye ought to walk," and he means thereby the whole conduct of life. "And to please God, that ye abound more and more." That is, that by more abounding ye do not stop at the limit of the commandments, but that you even go beyond them. For this it is, that "ye abound more and more." In what preceded he accepts the marvel of their firm faith, but here he regulates their life. For this is proficiency, even to go beyond the commandments and the statutes. For no longer from the constraint of a teacher, but from their own voluntary choice, is all this performed.
