When Jesus heard that, he said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.
John 11:4 (KJV)
It is the will of our heavenly Father that His glory be made manifest in and through His people. And so whether it be sickness, lack, anxiety, or anything else, God wants to use our challenge to manifest His glory in us. This means healing, deliverance, provision, soundness and protection.
