A worship service is convened with a call to worship. The people of God confess their sins as they prepare to enter the sanctuary. They then consecrate themselves as they sing praises and hear the Word preached. Having done so, they commune with God in the Lord’s Supper. At the conclusion of the service, they are commissioned to go out into the world to live as servants of Christ. Now I take it for granted that nobody is against us doing any of this stuff. Our grounding for this pattern in the sacrificial system of the Old Testament is found in the fact that the guilt offerings, the consecration offerings, and the peace offerings were presented to God in that order. The guilt offerings correspond to confession of sin, the ascension (whole burnt) offerings were consecration offerings, and the peace offerings correspond to communion. --Doug Wilson
