Suffering is God's design in this sin-soaked world (Romans 8:20). It portrays sin's horror for the world to see. It punishes sin's guilt for those who do not believe in Christ. It breaks sin's power for those who take up their cross and follow Jesus...there is no greater joy than joy in the greatness of God. And if we must suffer to see this and savor it most deeply, then suffering is a mercy.
