"Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance."
When you encounter trials in life, be glad. This will lead to spiritual maturity and inner peace. It is because your faith is tested because of this. So, this will be the reward.
Consider it a sheer gift, friends, when tests and challenges come at you from all sides. You know that under pressure, your faith-life is forced into the open and shows its true colors. So don’t try to get out of anything prematurely. Let it do its work so you become mature and well-developed, not deficient in any way.
