HEAVENLY FATHER, I would love to be a dad, to hold a sticky hand while we watch a ball game.But is Caitlin Williams's daughter coming into my arms at birth part of Your plan? Caitlin named me as the dad so her preemie could receive urgent medical care. That's why I brought the Williams women home with me until Caitlin gets back on her feet. I sense she's hiding something about her past - I wish she'd realize secrets can tear you apart.Now I can't imagine my life without them. I've even proposed to Caitlin - for the baby's sake, of course. But convincing Caitlin to make the three of us a family will be no easy task.
