As Israel remembers the foolishness of making and worshipping idols, it should inspire greater trust and confidence in God. When we think about the alternatives to following the LORD, it should make us follow Him all the more closely. Because God is the First and the Last, He lives outside our time-domain and can proclaim things before they happen. He can proclaim the things that are coming and shall come. This shows God really is who He says He is. The LORD makes us know through this whole passage, and in these verses to be the Redeemer, the Creator of each person, the Creator of all things (who makes all things), wiser and greater than anyone.
