Something fun you could do:

write together a letter to God, entrusting him with all your dreams, expectations and hopes as you start your marriage in the Church. Put it in an envelope and seal it. Keep it in a safe place and re-open it a year later on your first anniversary! You will be amazed at what God has done in your life!

You can turn it into a family tradition afterwards! We do this every New Year as a way to entrust the New Year to the Lord. We write down all our petitions then re-open it on December 31^st. We are always in awe in front of what he answered!
