One very wise man in the Bible was Gideon, and before Gideon made a decision, he put a fleece before The Lord.

He says in Judges, the Book of Judges, Chapter 6, and verses 37 to 40.

He said, “Lord, I just want to know what Your will is.” He says, “ I am going to put a fleece out tomorrow and he says, “ and I want dew and moisture to be on the fleece and the ground to be dry.”

The next morning, that is exactly what happened.

He got a bowl full of water out of the fleece when he wrung it out.

But still, he said, “Lord, please forgive me for being so hard-headed but I really need a second confirmation.” He said, “Tomorrow I am going to put the fleece out, and I want the fleece to be dry and all around it to be wet”, and sure enough it was.

A good idea is not always a God idea.
