Being 'called out of Egypt' is a great blessing for God's children. Israel thrived in Egypt despite being slaves. Evil men may try to eliminate God's people but they will fail in the end. Moses was to deliver God's people and to give them God's law. God gives us evidence.
Some people try to dismiss miracles as impossible or unnecessary.
A little thought however shows just how important the miracles are. They were evidence that God was at work in the prophets and in Jesus. Take heed watch and pray' is good advice for us, with Christ's coming so near. Jesus IS Son of God, the Saviour and coming King. The Exodus, accompanied as it was by many great miracles, demonstrated that God is the only God.
