Christianity is a very personal religion. (“I”...“I”...“I”; “I have sinned and I have been saved.”) Belief in Christ is a personal thing.
A sinner needs a Saviour—not a teacher or encourager, or perfect Guide to teach to do better next time.
Once after a missionary trip, we decided to swim on a mountain lake. Not knowing how to swim, but in the excitement of the hour, I jumped in.
Yelling and calling for help that day, I did not need a teacher showing me how to swim or a lecturer on my foolishness. What I desperately needed was a saviour who, without saying a word, would jump in and save me.
