The Lord’s Supper is a sign of God’s will toward man that He is gracious and desires to save us. In the Lord’s Supper, the Lord is giving out His gifts of Christ’s Body and Blood for the forgiveness of sins. “And just as the Word has been given in order to excite faith, so the Sacrament has been instituted in order that the outward appearance meeting the eyes might move the heart to believe [and strengthen faith]. For through these, namely, through Word and Sacrament, the Holy Ghost works” (Ap XXIV, 70).
The principle use of the Lord’s Supper is for God to give out forgiveness and create/strengthen faith in terrified consciences. Nevertheless, when we remember the benefits (which Christ purchased, and which He is giving out in this Supper) and receive them by faith in accordance with the words of institution, then by our use of the sacrament, there is added a secondary use: we praise God! Receiving the Lord’s Supper for the principle use which God intended has the effect of thanksgiving(a secondary use). The person receiving the Lord’s Supper as a sacrament, holds the gift in high esteem and praises God for His benefits. “And the Fathers, indeed, speak of two-fold effect, of the comfort of consciences, and of thanksgiving, or praise” (Ap XXIV, 75). The highest worship of God is to receive His gifts! “…so the reception itself of the Lord’s Supper can be praise or thanksgiving” (Ap XXIV, 33).
“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. We can, however, offer nothing to God unless we have first been reconciled and born again. 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 the will of Him that sent Me, that every one which seeth the Son, and believeth on Him, may have everlasting life” (Bente, Ap IV, Reply…, 189).
