“Paul, and Silvanus, and Timotheus, unto the church of the Thessalonians in God our Father and the Lord Jesus Christ:”
King James Version (KJV)
1:3 It is highly observable, that the apostle wraps up his praise of men in praise to God; giving him the glory. Your faith groweth - Probably he had heard from them since his sending the former letter. Aboundeth - Like water that overflows its banks, and yet increaseth still.
