Then Moses stretched out his hand over the sea, and the Lord drove the sea back by a strong east wind all night and made the sea dry land, and the waters were divided. And the people of Israel went into the midst of the sea on dry ground, the waters being a wall to them on their right hand and on their left.
The winds blew all night and the people didn't walk across until morning. God will make a way for you in advance; in preparation of your coming. You can't see it because like the wind, the hand of God is invisible. But you know that it's there when you see the results. A way made out of no way.
