I once spoke with a woman who was dying from heavily metastasized cancer.  She was worried that she would miss her daughter's wedding.  I talked to her about the wedding that really matters, the one that both she and her daughter would be at - the wedding from the parable Jesus told.  In this parable, the wedding stands for the final judgement.  We look at the way Christians need to be confident that they will get an invitation to this wedding and that they will be honored guests.
