What a great thing to hear as the final part of your marriage ceremony!
Sounds like something to be excited about.
I can't imagine being married and then reminded that this marriage that you have waited for and been excited for has, in essence, a divorce decree built in.
Is there more?
Part of what we believe, is that when we are married in one of our most sacred buildings, a temple, where only worthy Church members can go, that if we live worthily, we can be with our spouse for eternity.
Together forever. Part of the God's plan of happiness for us.
There's more. Lots more.
