The Israelites were in captivity in Egypt for hundreds of years. No one there was old enough to remember not being slaves. God, through the Passover, finally gives them their freedom. They all pack up their bags, leave their homes and head for the promised land. No matter how much God showed them miracles they soon forgot and wanted to go back home to Egypt. Well, after crossing the Red Sea there was no going back.
This in some way is the way we feel at times. God has asked us to give up our home and way of life and follow Him. Not following Him would be going back to being slaves to sin. It would be easy to go back to the status quo, to our normal lives and not go where God is leading us. No matter how clear it is for us to see the path that God is leading us down, it would be easy to turn our heads and take our eyes off of Him. God never promises that the path will always be level and smooth. We sometimes have to get down on our hands and knees to pray to see where He is leading us.
Just like the Israelites, we must keep our eyes on Him. God will never lead you down a path of destruction. He never promised us that it would be easy but what a reward it will be to be with Him. The promised land is not Guatemala nor was it where the Israelites ended up. The promised land is being in constant communion with Him.
