That was no advance. One could believe from reading Hebrews 11 that God's measure of ministry is the courage to go out and to go forward at His call. Days of deliberating His call must yield to days of decision, or they will yield to days of deception. The gallery grows larger and the stage grows smaller. It is returning to an earlier state.
Regression romanticizes yesterday and doubts tomorrow.
Regression is responding to God's call with unbelief. One may believe that they can stand still when God says go, but in fact, they have already begun the backward journey. To stand still in a changing world is to become backward. When one obeys and goes forward, there is grace for the journey. Progress is with God's help.
