(1) The service begins with The Preparation, where we confess our sin to God and receive His forgiveness. Thus cleansed and forgiven, we are free to come into His presence and receive His gifts. You will notice that it is at this point that the pastor first walks back to the altar, to show this in a visual way.
(2) The service continues with The Liturgy of the Word. Of primary importance in this part is that we hear the Word of God in the reading of the Scriptures and the proclamation of the Gospel in the sermon. In these you hear not the words and opinions of man, which change and err, but the voice of our Lord, eternal and truthful, speaking to His own.
(3) After receiving the gift of God's Word, The Liturgy of the Sacrament, or Holy Communion, is celebrated. Here we enter into the most intimate union with our God as we actually eat His body and drink His blood. With this eating and drinking, God promises us His forgiveness, life, and salvation. Having received these and the fullness of His gifts, we then joyfully depart back out into the world with His blessing, to share His Word and forgiveness with others.
