The Lord Himself preaches the Law's call to repentance in these two texts. And the greatest repentance (literrally, "re-thinking" in Latin, "changed mind" in Greek, though my favorite is Hebrew's "shoov" = to be turned) is turning away from the thought that we are able to get ourselves out of this mess.
I can't help but think of the church seasons when these texts are used. Though the Christian Church Year is a tradition of man, it points to the Lord - the One who comes (advents) and reveals (epiphanies) Himself as the Savior who makes right all that has gone wrong.
The Lord shine His Gospel light upon you to scatter your darkness, dear reader.
