When God is about to perform any great work, He generally permits some great opposition to it. Suppose Pharaoh had acquiesced in the departure of the children of Israel, or that they had met with no difficulties in the way. They would indeed, have passed from Egypt into Canaan with ease, but they, as well as the church in all future ages, would have been great losers. The wonder-working God would not have been in those extremities, which make His arm so visible. A smooth passage here would have made but a poor story.
– John Newton
