Many people have asked why I stayed and fought for my marriage. The answer to that is as complicated and intricate as trying to understand what makes a massive ocean pull back and stop at the shore. Apart from God, who can ever truly understand a thing like that? There was a season that it wasn't reasonable or responsible to stay. Just like when the ocean doesn't respect the boundary of the shoreline and hurricane conditions force evacuations. So there were long stretches of silence, separation, and seeking wise counsel. But then the shoreline became safe again. And I had a choice. I was offered a second chance at moments like this one. Simple moments that make complex situations less complex. Forgiveness is a process. Healing is a long journey. And I'll never ever criticize another person for choices they made that were different than mine when placed in the same horror and heartbreak as me. Or maybe they had no choice at all. I have nothing but tender love and understanding. It's a brutal walk. So why did I stay? I was given that chance. I love Art. And I've discovered imperfect love is still full of sacred possibilities, redemptive strength, it's own kind of purity, and moments like the one pictured here.

TerKeurst announced last June that her husband, Art, had been unfaithful and their marriage was over.

But the Lord had other plans. In December, the couple recommitted to each other and shared the stunning images on Instagram.

TerKeurst's journey through her husband's betrayal and the Lord's redemption is captured in It's Not Supposed to Be This Way.
