In Exod. Chapter 14, the Bible gives the account of the Hebrew people crossing the Red Sea on dry ground.
After being set free from slavery in Egypt, the people were traveling toward the promised land of Canaan, but became trapped between two mountains and the Red Sea. The Egyptian army was pursuing and would soon overtake them and punish them severely for escaping.
The people cried out to God for help in this hopeless situation, and Moses said, “Fear ye not, stand still, and see the salvation of the Lord.” (Exod. 14:13)
Then Exod. 14:21 says that the Lord caused the sea to go back by a strong east wind and the people crossed over on dry ground. When the Egyptians tried to follow, God sent the walls of water back together and drowned the army.
This story should remind us that we can call on God knowing that he can provide a way out of whatever situation his people may be in. He has already provided a way out of the penalty for sin by letting Jesus Christ dies for anyone who will believe in him.
