Psalm 136:15

but swept Pharaoh and his army into the Red Sea;
His love endures forever.
(NIV)

What a great end to such a stubborn pharaoh. To watch his entire army wash away.

Pharaohs believed that they were gods. And to have some hebrew slave come in and tell him that the God of gods has demanded to let His people go. It is no wonder the pharaoh kept saying no. Why should the god of the Egyptians give in to the God of the Hebrews? It made no sense to him.

But pharaoh was no god.

Neither are we. We cannot stand up against the God of the Universe. We try to set ourselves up as our own gods in our own hearts. We try to run our lives, but the one true God will wash all of our defenses away, like He washed Pharaoh's army away, and take his rightful place. (or He will leave you to your devices and let you destroy yourself.)

C.S. Lewis once said,

There are two kinds of people, those who will say to God, "Thy will be done." or those to whom God will say, "Thy will be done."
