Carol needs to hear his message, needs to repent, needs to be forgiven. She has not done anything that would make the top 100 list of sins. She has no skeletons hidden in her closet and nothing in her life that they couldn't print in the local newspaper. The closest thing to a sin as most of us would define sin is a mild grouchiness that never quite goes away. Nevertheless, the grouchiness is a symptom of the black hole in her heart where once upon a time joy lived.
Advent begins with an invitation to repent and be forgiven.
Whether or not it is a welcome message, it is surely one we need to hear. So often the Christmas season is about how powerful we are, what we can do, how much we can afford, what we can give. The focus is on us and what we can do to make everything right, right now. It's as futile as trying to plant a garden in Minnesota in December. And the seeds you plant are very unlikely to grow.
