The man is not in heaven. Jesus was telling a parable.
So SFIC where is the wedding feast if not in heaven?
Jesus is telling you an earthly story to help you understand a spiritual reality. This is what's going to take place in heaven after the judgment seat. There are going to be some that think they are prepared for the wedding and then there are going to be those that ARE prepared for the wedding.
It's amazing that something is so absolutely clear and yet you continue to deny it to hold on to your tradition.
