We prepare for Christmas by repenting. Repenting in the Biblical sense is more than having a change of heart or a feeling of regret. It is more than a New Year's Eve resolution. Repentance is a turning away and a turning back. A turning away from sin and a turning back to God.
Bishop Joe Pennel of the Virginia Conference of the United Methodist Church, once attended a Christmas worship service in Bethlehem at a place called Shepherd's Field. As he heard the songs of the season, he thought to himself and later wrote: "I did not look to God and say: See how virtuous I am. I did not utter: God, pat me on the back for all of the good things I have done. I did not pretend by saying: God, look at all of my accomplishments, aren't you proud of me? Indeed, I found myself asking God to forgive me of my sins. That is how it works. The more we turn away from Christ the more enslaved we become to the power of sin. The more we turn to Christ, the more free we become from the bondage of sin. Turning toward Christ enables us to repent."
Someone once said half jokingly: If we are not careful, John the Baptist can take all of the fun out of Christmas. I disagree. I think that it is John's message that puts the joy into Christmas. For it is his message that calls us not to the way that Christmas is, but that the way Christmas ought to be. Christmas ought to be free from guilt and self-absorption. For that to occur there must be repentance.
