God uses chronic pain and weakness, along with other afflictions, …for sculpting our lives. Felt weakness deepens dependence on Christ for strength each day. The weaker we feel, the harder we lean. And the harder we lean, the stronger we grow spiritually, even while our bodies waste away. To live with your 'thorn' uncomplainingly -- that is, sweet, patient, and free in heart to love and help others, even though every day you feel weak -- is true sanctification. It is true healing for the spirit. It is a supreme victory of grace. The healing of your sinful person thus goes forward, even though the healing of your mortal body does not. And the healing of persons is the name of the game so far as God is concerned.
