What does the Bible say about sickness and God's love?

The Bible clearly states that all whom the Lord loves will experience sickness, but this is not punishment; it is mercy. According to John 11:1-4, the sickness of Lazarus, whom Jesus loved, was for the glory of God. It is essential to understand that while all humanity suffers due to the curse of sin, for the child of God, sickness serves a divine purpose in glorifying Christ. In Romans 8:28, we see that all things work together for good for those who love God, emphasizing that sickness, while painful, is under God's control and is meant to display His glory.
