In this marriage devotional , you will find deeper spiritual and personal application for the principles in the book A Lifelong Love by Gary Thomas. Draw closer even closer together as you reflect on this devotional content. Build the Right Foundation, marriage is designed by God, a mark of His kindness because He allows us to know the joys of intimacy and family life. Yet even the best of marriages is a miserable substitute for the ultimate reality of living for God.

That's what God provides in a marriage based on Him. "If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing."—John 15:5. What do you think it looks like to have God as your magnificent obsession?
