Without Evil, No Christianity!

Do you find this theological proposition startling, even shocking?  It was for me when I first began to consider it.  So did evil make Christianity possible, indeed necessary?  Let’s think more seriously about this possible interrelated interconnectedness.

True or False?  Without evil, there would have been no progression of covenants.  Without evil, no need for the Law and the Prophets.  Without evil, no reason for Christ to have come.  Without evil, no cross.  Without evil, no redemption.  Without evil, no pouring out of the Holy Spirit.  Without evil, no Bible.  Without evil, no Church.  Hence, without evil, there would be no Christianity.  Agree or disagree?

What do you think and why?
