The book mentions that financial issues are one of the most common sources of conflicts in marriage that lead up to divorces. Consequently, managing finances in God's way is vital for a healthy marriage as it's God's idea to enjoy it.
For this, the book suggests couples should know each other through candid communication as they come from a different financial background. Together, they should set a goal and have 'Money dates' where they discuss economic issues and celebrate achievements. The book also offers a visual Money Map, where couples can use to write off debts and a chart for controlling monthly spending plans.Furthermore, it separates marriage phases (i.e., engagement, hitched, midstream, and empty nesters) and discusses what to do in those stages. Lastly, the book mentions the biblical view of Stay-at-home moms and dealing financially with ex-spouses.
Reading it, I didn't found any 'a-ha' moments, but I still recommend as it has valuable insights.
