If you have been following my posts, you may have noticed me talking with Mark about the fact that a marriage requires two people to agree not to divorce.
I can decide alone to pay my tithing, keep the Word of Wisdom, go to church, and all the other commandments.
Marriage is the only requirement for exaltation that requires two people to decide. I cannot decide alone that I will have a successful marriage. It only happens if you and I decide together.
You may remember also that President Kimball gave a "guarantee" for a successful marriage.
Can you remember the 4 parts of the guarantee?
