Why

"The battles God calls us to, the woundings and cripplings of soul and body we all receive, cannot simply [only] be ascribed to our sin and foolishness, or even to the sin and foolishness of others.

"When Jesus and the disciples were on the road one day, they came upon a man who had been blind since birth. “Rabbi, who sinned, this man or his parents?” they asked him. “Neither this man nor his parents sinned,” said Jesus, “but this happened so that the work of God might be displayed in his life.” And with that, Jesus spat on the ground, made some mud to place on the man’s eyes, and healed him (John 9:1–7).

"Many of us who are reading these words have not yet received God’s healing. The display of God’s works through our wounds, losses, and sufferings is yet to be revealed. And so, we groan and we wonder."
