If you are a person of faith, and have a family, friends that are your family, share your Christian faith, create activities to share it. Why does Advent matter? Before the actual wedding, you have a lot of pr-wedding activities and preparations. Reason being that you need to really let it sink in that this momentous event is going to be taking place. Sometimes those around us make us nuts and add to the stress, but if you have a group of people around you that work to ease stress, then those things matter, as does counseling prior. To help have it sink in that you are awaiting the birth of the Savior, Christ, Lord, King, a calendar of things you can do is a good idea. I hope you find these ideas helpful and fun.
Namaste, Shalom and Amen
