There is nothing too hard for God. He did it once in the past and can do it again now and in the future. He is able.
Read: Exodus 15:21-27
21 And Miriam sang this song:
“Sing to the Lord,
for he has triumphed gloriously;
he has hurled both horse and rider
into the sea.”
22 Then Moses led the people of Israel away from the Red Sea, and they moved out into the desert of Shur. They traveled in this desert for three days without finding any water. 23 When they came to the oasis of Marah, the water was too bitter to drink. So they called the place Marah (which means “bitter”).
24 Then the people complained and turned against Moses. “What are we going to drink?” they demanded. 25 So Moses cried out to the Lord for help, and the Lord showed him a piece of wood. Moses threw it into the water, and this made the water good to drink.
It was there at Marah that the Lord set before them the following decree as a standard to test their faithfulness to him. 26 He said, “If you will listen carefully to the voice of the Lord your God and do what is right in his sight, obeying his commands and keeping all his decrees, then I will not make you suffer any of the diseases I sent on the Egyptians; for I am the Lord who heals you.”
27 After leaving Marah, the Israelites traveled on to the oasis of Elim, where they found twelve springs and seventy palm trees. They camped there beside the water.
