Derek Prince:

Gideon

In Judges 6:34, we read about Gideon: Then the Spirit of  the LORD came upon Gideon,  and he blew a trumpet,  summoning the Abiezrites to follow him.

The Spirit of the Lord came upon Gideon and made him the mighty leader  that he was. Before that, he was a timid young man, cowering at the winepress,  unable to do anything effective. But he was changed by the Spirit of God coming upon him.
