All power belongs to God. There is none powerful and supreme to overturn what He wants to do. Exodus 7 teaches us to trust Him and see His marvelous works.
God deals with our doubts
What do we do with our doubts when God's mission is at stake? In Exodus 6, we learn that Moses had complaints and doubts but God helped to revolve them and put His word on his mouth.
Empowered to serve
If Israel will move from Egypt to the promised land, they will need a leader to do the work of God. Exodus 3 shows us how God called and empowered Moses to serve.
