The writer of this psalm recounts points of Israel’s history of deliverance from Israel by describing the earth’s reaction to the events. He begins by setting the stage:
1 When Israel went out of Egypt,
The house of Jacob from a people of strange language,
2 Judah became His sanctuary,
And Israel His dominion.
From there he describes how the Red Sea and the Jordan river turned back so Israel could cross. The mountains skipped, the sea fled, the earth trembled, a rock split and gave water to Israel. This short psalm describes the mighty power of God that was evidenced through the deliverance and wilderness journey of Israel.
When you are on your journey, uncertain of the destination, or at least uncertain of the path to reach it, God surely is working on your behalf as a child of God. He is parting seas, moving mountains, bringing forth water in your thirsty times. The crux of the issue is this: God is your help in trouble; He is your Provider, your Protector, your Waymaker. Instead of spending unproductive time on fear, doubt, and worry, trust in Him and move further down your path to the land which He promised you. You will survive, and you very well may thrive on your way to the Promised Land!
