Often here that.
There is a story about a new preacher.

The church was packed at his first service.
His sermon was brilliant - so next week the church was filled again.

He gave exactly the same sermon.
Not many people at the next service -
when he gave exactly the same sermon.

When asked about it he said words to the effect that,
when people start putting into their lives what I have suggested
I will give a new sermon.

I often I get emails saying that they heard me say some particular thing
many times before, and hearing it this time, it clicked.

Happy clicking...
