Pursued by Egypt, fearing for their lives, the people of God begin to clamor. But God doesn't intend to abandon his people.
Moses calls them to stand firm and see the salvation of the Lord. They need not fight and they need not cry out to God in case he'd forgotten them, they need only wait and watch the salvation of the Lord.
Isn't this same encouragement ours?
So often we would turn to despair and doubt instead of faith. We despair that our lives possess any hope of change. We doubt that our Lord actually cares what happens to us.
But the God of the Bible is not a God of despair and doubt. No circumstance has ever overwhelmed him. Neither our weakness nor the world's hatred can cause him to falter. No doubt changes the reality that our Savior died for us and God the Holy Spirit now dwells in us.
Fear not, child of God. Stand firm. The Lord will fight for you.
