The Confessions on Worship

Thus the worship and divine service of the Gospel is to receive from God gifts; on the contrary, the worship of the Law is to offer and present our gifts to God…This passage, too, brings the greatest consolation, as the chief worship of the Gospel is to wish to receive remission of sins, grace, and righteousness. Of this worship Christ says, John 6, 40: This is he will of Him that sent Me, that every one which seeth the Son, and belieiveth on Him, may have everlasting life. AP III, paragraph 189, Triglotta, pg. 207
