“Many are called, but few are chosen.” Not everyone goes to heaven. The Lord has atoned for the sins of the whole world. All are invited. No one need pay for his own sins, go unclothed or hungry, but some choose to anyway. They refuse the invitation and they stay out of heaven.
The Lord is into weddings. He arranged the first one in Paradise and He performed His first miracle at one in Cana. He is into gatherings around food, into wine and laughter, and celebrations.
That His coming to earth, becoming a Man, should be likened to a wedding should be no surprise, nor should it be a surprise that this be celebrated with a feast.
Our Lord preaches the Law to the lawyer, not to debate, but so that he would see his need for the Christ who is David’s son and David’s Lord.
