Another tradition is that God chastises His children with  sickness. They quote part of Hebrews 12:6-8, which says, "whom the Lord loves he chastens".

God does chasten those whom He loves, but not by making them sick.

The word "chasten" here means, to instruct, train, discipline, teach or educate" like a parent with a child. A parent would go to jail if they did such to their child. God is not a child abuser!
