God drew a line in time at the cross.

When Jesus died He cried out " It is finished" - all that He came to do had been accomplished. He had taken upon Himself all of our sin, all of our shame, all of our sickness, all of our sorrow, all of our frailty and weakness.

In Exodus 15:26 God says "I am Yahweh Ropheka" A translation of the Hebrew is "I am the Lord who heals you." This is the first revelation that God gives in the bible through one of His names of his nature and character.
