You are in the place where the ROCK was smitten. His death is your death. So since you died you must be a new creature. You already got what you sinful life deserved in Christ. They tell you to face your fears from your past.
Some preachers smite the rock again and again.
When people sin after they are saved, preachers smite them again and again. Give the word, the second time and the third, Moses. Just teach them. If you feel no-good , then you will think, I might as well sin. How much worse can I get anyhow, since I am already no good.
