A Preacher Paints the Church

There was a preacher that needed to paint the temple so he got the paint, paint brush and ladder and went to painting the buliding. When he got about one third done he realized he was running low on paint so he got the paint thinner and thinned the paint.
When he was about two thirds done he did not know if he was going to be able to finish, he was really running low on paint so he got the Paint Thinner and Thinned the Paint again.
Finaly he finished and when he was at the top of the temple on his ladder a thunderstorm came and the rain fell and washed off all the Paint on the Temple.
Then the clouds parted and He heard a Voice come down from Heaven saying Re-P(ai)ent and (th)Sin no more.
