You might suffer, even to the point of losing your life, for preaching the Gospel. In that situation, God promises that he'll comfort you. Paul teaches us that if we find ourselves under religious persecution, we can turn to God and be strengthened. As we're strengthened, it helps us persevere, and we come out with hope and patience. But you can not say that God will mess around with your life's circumstances, to make you suffer, to teach you patience.
