If we ask ourselves what we would like to give them, beyond the gifts we have chosen from their gift registry, we may find that we will each be able to name our spiritual gift, or gift of well-being, and thereby give it more effectively.

Not bad. What a beautiful desire to select and give to a bride and groom.
