“Our Lord is the Lord who serves. Jesus Christ came into the flesh not to be served, but to serve and to give His life as a ransom for many. On the cross He offered Himself as a spotless sacrifice for the sin of the whole world. […]
“Our Lord serves us today through His holy Word and Sacraments. Through these means, He comes among us to deliver His forgiveness and salvation, freeing us from our sins and strengthening us for service to one another and to the world. At Holy Baptism, He puts His name upon us, pours His Holy Spirit into our hearts, and rescues us from sin, death, and the devil. Through Holy Absolution, He pronounces His forgiveness again and again. With His holy Word, written in Scripture and preached into our ears, He daily proclaims His abiding love for us through all the joys and sorrows of life in this world. In His Holy Supper, He gives us His own body and blood to eat and drink as a priceless gift to nourish and strengthen us in both body and soul.
“The Lord’s service calls forth our service—in sacrifices of praise and thanksgiving to Him and in loving service to one another. Having been called, gathered, enlightened, and sanctified by the Holy Spirit, we receive His gifts with thankfulness and praise. With psalms, hymns, and spiritual songs, we joyfully confess all that God has done for us, declaring the praises of Him who called us out of darkness into His marvelous light. Our song joins with the song of every saint from every age, the new song of Christ’s holy people, declaring: “Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing!” (Rev. 5:12).” […]
“This heritage of word and song has been highly valued throughout the history of The Lutheran Church—Missouri Synod.”
