Some were mocked, and their backs were cut open with whips. Others were chained in dungeons. Some died by stoning, and some were sawed in half; others were killed with the sword. Some went about in skins of sheep and goats, hungry and oppressed and mistreated. They were too good for this world. They wandered over deserts and mountains, hiding in caves and holes in the ground.
All of these people we have mentioned received God’s approval because of their faith, yet none of them received all that God had promised. For God had far better things in mind for us that would also benefit them, for they can’t receive the prize at the end of the race until we finish the race.
Hebrews 11:36-40

There is no such thing as pointless pain in the life of the child of God. How this has encouraged and strengthened me in the valleys of suffering and pain! In this essay I'll be discussing the value of suffering, an unhappy non-negotiable of life in a fallen world.
Suffering Prepares Us to Be the Bride of Christ

Among the many reasons God allows us to suffer, this is my personal favorite: it prepares us to be the radiant bride of Christ. The Lord Jesus has a big job to do, changing His ragamuffin church into a glorious bride worthy of the Lamb. Ephesians 5:26-27 tells us He is making us holy by washing us with the Word--presenting us to Himself as a radiant church, without stain or wrinkle or any other blemish. Suffering develops holiness in unholy people. But getting there is painful in the Lord's "laundry room." When you use bleach to get rid of stains, it's a harsh process. Getting rid of wrinkles is even more painful: ironing means a combination of heat plus pressure.
