And the Spirit of God moved upon the face of the waters. — Genesis 1:2
Throughout the Bible, in both Old and New Testaments, in both Hebrew and Greek languages, the word translated “Spirit” is the same used for Breath and Wind. Why?
Part of the answer, I believe, is that wind, breath, spirit is unseen and uncontrolled. It can be felt on our skin, it can be heard blowing through the trees and tall grass, we even try to track it with radar, but it goes where ever it goes without or control, approval, or direction.
God’s spirit is like that and so are his followers.
The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit — John 3:8
He moves and we benefit. We pray for it, wait for it, work with it or against it, but we don’t control it, and we don’t control those following him.

God’s object lessons can be strange. In the Old Testament, when God’s people complained poisonous snakes slithered out and bit them.1 God’s cure was to take an image of one of those snakes, put it on a pole and look at it! Those who looked lived and those who refused to look died.
