God has led the Israelites to the Red Sea and they seem to be trapped, pursued by Pharaoh and his army. Moses and the people are almost in despair when God commands them to go FORWARD because the way was THROUGH the sea. God provides a way for them and He provides a way for us to walk in faith, following our redeemer in the way - so that we can leave our old lives behind and be made holy! This is a picture of baptism!
