1 O that you would tear open the sky and come down, so that the mountains would shake at your face– 2 like when fire kindles brushwood and the fire causes water to boil– to make your name known to your enemies, so that the nations would scurry at your presence! 3 When you did awesome deeds that we did not expect, you came down, the mountains shook at your face. 4 From ages past no one has heard, no ear has perceived, no eye has seen any God except you, who works for those who wait for him. 5 You encounter those who enjoy doing right, those who remember you in your ways. But you were angry, and we sinned; because you hid yourself we transgressed. 6 We have all become like one who is unclean, and all our righteous works are like a menstrual cloth. We all fall like a leaf, and our iniquities sweep us away like the wind.
confessions of the fallen
After Isaiah had complained to God that his people are far from the righteousness he expected, he now confesses just exactly how that happened. He wishes that God would make another one of his amazing miraculous encounters, like he did in the old days. But he also know that God chooses to encounter those who enjoy doing right and remember his ways. That is hardly the case for Isaiah’s generation. Instead, Isaiah confesses that God became angry and hid himself, and the people got lost in their own disobedience. Now, they are like a leaf that has fallen, and is swept away by those same sins. Any attempt at works of righteousness, or works of law, is like a woman putting on a menstrual cloth during her period. It merely covers, but does not cleanse. That is how Isaiah sees his generation. It is very much like this generation, isn’t it?
LORD, we do not deserve a miraculous encounter. But we need you. Come and rescue us from our own sinfulness and neglect of your ways!
