I think it is most appropriate today to begin our reflection on the Scriptures by focusing especially on the first lesson, where Isaiah is trying to reassure people that God is about to do something new, if only they have the courage to respond to what God is doing. We should remember that these are people who have been driven out of their own city and land. Jerusalem was destroyed and the temple was left in flames. They had to go off into exile, and were in exile for 80-some years. By now, they had become accustomed to the way things are.
Isaiah is preaching to them that it is time to go back and have your place again, and live where God gave you the land to be yours, but they were hesitant. They'd gotten used to the way things were. That's when Isaiah said, "Do not dwell on the past." They were thinking back to the time when Moses had led them out of Egypt, freed them from slavery and established the Jewish law. They were trying to hang onto that.
God said, "Look, I'm doing new things. Now it springs forth. Do you not see?" Further on, He said, "I have formed this people for myself. They will proclaim My praise. Neither have you satisfied Me with the fat of your sacrifices. Instead, you would burden Me with your sins and wearied Me with your offenses. I am the one who blocks out your offenses for My own sake. I remember your sins no more." God is saying to them, "There is a new opportunity now. Let go of the past. Be ready to follow where God is leading you now."
