Read Psalm 6, 41 and 60
In the Old Testament when they had sinned, they felt it in their bones and in the land. We still do so today, (arthritis can be because of unforgiveness and uneasiness on our part) but if we turn to Jesus, He took all our sins and diseases. Before Christ they had to turn to sacrifices morning and night, and sacrifices for when they sinned, every time with a contrite heart; today our sins and diseases are covered by the Blood of the Lamb, we can do no more, but accept it.
Jesus has done it all for us, He is not going to the cross again.
