Marriage is a choice. It is not a religious or social obligation and it doesn't complete us, but if we do get married, the marriage can be happy and prosperous. "Marriage: Sink or Swim" touches on spiritual principles that have proven over time to be effective in smoothing out a relationship. To back up the spiritual principles, other chapters are added to the book: "Footsteps of Truth" and "Debunking Misconceptions about 'Science and Health.'" Cheryl also included in the book an essay "Calling out the Naysayers" to empower the reader not to let peer pressure disturb your spiritual progress.
