I just received a copy of “Marriage on the Mend” by Clint and Penny Bragg, marriage missionaries. I have read a couple of chapters, and it looks like a great resource for those who have decided to reconcile their relationship, or for those who want to grow their marriage to new levels so they never go through a terrible time of struggle. They share their story, resources, exercises, and other testimonies of healed marriages as an encouragement for couples to stay together and work things out.
Clint and Penny were married, then divorced, but after 11 years and 3000 miles of being apart, through a miracle from God, they reconciled. I know them personally and they have a passion for seeing marriages healed.
