Glen Clary speaks about the biblical basis and covenantal context of the call to worship and benediction. These elements of worship are rooted in Christ's work on behalf of his covenant people.

In the call to worship, God calls his people to have covenant communion with him in his heavenly temple. He calls us to enter his house—to draw near to him—to have communion with him.

The benediction is the bestowal of the covenant blessing by the successful probationer. Had Adam obeyed, he would have received for himself and for all his posterity the covenant blessing. The covenant blessing would be given to those whom he represented in the covenant of works on the basis of his obedience. Now, Christ as redeemer and mediator of the covenant, the obedient federal head (successful probationer) receives and bestows the blessings of the covenant.
