When Caleb learns the book's daily challenges are tied into his parents' newfound faith, his already limited interest is made smaller still. Even though he wants to stay true to the promise to his father, Caleb becomes frustrated time and time again. He finally asks his father, "How am I supposed to show love to somebody who constantly rejects me?" When his father tells him that this is the love God shows to people, Caleb makes a life-changing commitment to love God. And, with God's help, he begins to understand what it means to truly love his wife. But, he is unsure if it's too late to "fireproof" his marriage.
