As in the previous psalm, we see a heavy emphasis on the miracle of crossing the Reed Sea. More than once some writer has marveled at the very thought of something so unprecedented, and we are called to wonder how anyone who walked through on that dry seabed could forget and then doubt God. But we are also told repeatedly that Israel was a demonstration of God’s holiness precisely because they were the most difficult nation He could have chosen. Yet again, in humility we have to wonder if we aren’t sometimes just as difficult for other reasons now that He has included all nations in His covenant in Christ.
The psalmist begins with an eloquent call to worship, including his thesis on the mercy of God. Notice how he opens wide the door to anyone who senses a call to join this celebration. Do you want to be a part of His people? It starts with humbling yourself before the God of Creation and accepting His invitation to join His household of faith. The focus is not on the particulars of the Law, but on a sincere desire to bless the Lord.
