Christ shall be magnified in my body, whether it be by life, or by death. Because we live in a world where Christ is thought to be small. Our response to suffering enlarges Christ. One doctor friend accepted Christ as he watched a dying patient glorify God. The Lord uses pain as part of the process of sanctification and we are brought closer to God.
Many people come to salvation in time of pain and distress.
We come to understand the serious nature of sin as that sickbed teaches us far more than a sermon. The wicked at times accuse Christians of serving the Lord because of His blessings or for other selfish reasons. We should submit to our employers, whether they are considerate or harsh. The suffering of the Christian often seals their lips and perhaps will allow us to win them to Christ by our good example. When a believer suffers, yet like Job of old, holds fast to his integrity, the world takes notice.
