When our son was struggling with heroin addiction, if you had told me God would one day use our experience to encourage other families who face these kinds of battles, I would have had trouble believing it. God has a way of bringing good out of difficult circumstances that isn’t always easy to see when you are going through them. The apostle Thomas also didn’t expect God to bring good out of the greatest challenge of his faith—Jesus’s crucifixion. Thomas wasn’t with the other disciples when Jesus came to them after the resurrection, and in his deep grief he insisted, “Unless I see the nail marks in his hands and put my finger where the nails were . . . I will not believe” (John 20:25).
