Exodus 13:17 And it came to pass, when Pharaoh had let the people go, that God led them not through the way of the land of the Philistines, although that was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt:
As God takes His people out of Egypt He carefully leads them only into what they are ready for and able to handle. He knew that if they had to go into battle they might become so afraid that they would return to Egypt.
The wild part of this story is that we all know that they will soon be a great warrior nation. They will defeat their enemies and be greatly used of God. But now God knows that they are not ready.
Sometimes there is a quicker way to get there but you are not ready to take it. They could have gone on quickly but they would not have been ready.
Could it be that God is preparing you for things tomorrow that are more than you could handle today?
