How do we know that God uses sickness for our good?

Romans 8:28 states, 'And we know that all things work together for good to them that love God, to them who are the called according to His purpose.' This verse assures believers that even sickness, pain, and trials are under God's sovereign control and serve to shape us according to His will. They can teach us reliance on Him and strengthen our faith. Instances of trial can lead us to deeper fellowship with Christ, as we learn to depend on His grace through difficult times, and ultimately glorify Him.
