But Harold Best suggests we should think of these instead as a call to continue worshiping. There can only be one call to worship, and this comes at conversion, when in complete repentance we admit to worshiping falsely, trapped by the inversion and enslaved to false gods before whom we have been dying sacrifices. This call to true worship comes but once, not every Sunday, in spite of the repeated calls to worship that begin most liturgies and orders of worship. These should not be labeled calls to worship but calls to continuation of worship.2
