The memory is vivid. My wife Merryn and I sat in emotional pain, talking. “If this really is our last chance to have a baby and it doesn’t happen,” Merryn said, “I need something else.” We’d spent the past decade trying everything to start a family—IVF treatment, healing prayer, adoption—all without success. We now awaited the result of one final IVF round. “If it doesn’t happen,” she said, her face downcast, “I have to have something else to look forward to.”
