Our call is to do God’s will, like the our father says I will be done on earth, as it is in heaven, but don’t let anyone pretend this is not difficult. It is very difficult Joseph and Mary found it difficult but because of their following God’s will great things happened. King Ahaz in the first reading, finds it difficult and because of his not doing it great suffering, an evil came upon his people. God gives us free will, and it’s hard to use that to do his will, but he knows that and he wants to help let us ask for that help, if even to do it a little bit better in one area of our life.
