“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.”
This comes from Harold Best’s book, Music Through the Eyes of Faith, which is also on the Books You Should Read list.
