You need only be still

Exodus 14:1-31
Moses said to the people: Do not be afraid. Stand firm and you will see the deliverance the Lord will bring you today. The Lord will fight for you; you need only be still.
Why are you crying out to me? Tell the Israelites to move on. God said to Moses.
When the Israelites saw the great power the lord displayed against the Egyptians, the people feared the Lord and put their trust in him and in Moses his servant.
Hemmed in between sea and mountains, with water before them and Pharaoh's forces at their backs, the people of Israel meet their first big test of faith - and they panic, crying out to God and accusing Moses of betrayal. But God drives back the waters so that they can cross in safety, sending a wall of water rushing down upon Pharaoh's forces, and Israel learns the truth of Moses' words: "The Lord will fight for you; there is no need for you to do anything"
Pharaoh is not said to have drowned, nor are all Egypt's chariots lost. Victory is won at Pharaoh's expense, and the detachment which pursues the runaway slave into the water is swept away - a bad enough blow.
Why?
God will fight for you, God is my deliverance; I need only be still.
1) Do not be afraid 2) Stand firm 3) Be still 4) Keep move on are the rule to serve the Lord.
How?
God is my deliverance, my fortress, and my way. Trust in Him and fear Him.
