Vision is accompanied by suffering. More precisely, Christian vision includes suffering (1 Peter 2:21). As sojourners, those who want to live a godly life (want to live for a vision given by God) will suffer. If you are not suffering for your vision, either your vision is not from God, or you are not living for your vision.
Vision grows through suffering. When we face suffering, we pause and think. Through the process that we evaluate what is important and what is not, what is to be kept or what is to be cut out, we learn how precious our vision is. Apostle Paul learned his vision is more important than his life through those sufferings that he had borne.
Vision overcomes suffering. Paul didn't know what to come in Jerusalem, yet he is going. Likewise, being faithful to the vision is more important than achieving the goal. And it always bring the victory because our victory is not what we achieve but the faithfulness to our vision.
