Isa 43:18 – Remember ye not the former things neither consider things of old.

13:19 Behold, I will do a new thing, now it shall spring forth, shall ye not know it?  I will even make a way in the wilderness, and river in the desert.

Forget your past experiences; God will restore your health unto you, even if your present situation looks terrible.  He will make a way where there seems not to be a way.
