Place yourself into the position of the soldiers that went to battle alongside Gideon. You are part of the biggest army that the nation of Israel has ever been able to assemble, and you are going to defend your nation against these enemies that seemingly never stop coming to attack your nation.

All of a sudden Gideon comes from some quiet time, and he tells half of the army to go home. You are still one of the lucky ones that will be part of the army to defend your nation.

This scenario plays itself out a couple of time, until there is only about 300 men left. The hope that you had to win this battle is all but gone, you are starting to shake in your sandals, but still you keep a little bit of faith. You do however think how crazy this Gideon is, this man that was nothing before this battle.

All of a sudden this man comes from another session of quiet time, and he tells these 300 men to leave their swords at home.

What the heck!

Is this man totally crazy?

After the battle these 300 men can't stop talking about how amazing God is. That He helped them defeat this army with vases filled with fire and some trumpets. All of these men have forgotten about the doubt that they had before they walked into this battle, with no weapons but musical instruments.

If you read the Bible, it is filled with heretics. With people that went against all common sense, but in the end did great things.
