Isaiah 58:8
and your healing will quickly appear

This one is pretty straight forward. Now, while you are fasting, is the BEST time to pray for healing. Hannah fasted and prayed because she was barren. God heard her cry, healed her and gave her a child. (1 Sam 1:7) Our God, our savior, is the same today as He was yesterday and He will be forever. Pray for miraculous healing, for yourself or someone else. I think, too often, we don't pray for healing. Mostly out of doubt. Why? The scripture makes is clear,

Is 53:5 But he was pierced for our transgressions,
he was crushed for our iniquities;
the punishment that brought us peace was upon him,
and by his wounds we are healed

Mal 4:2
But for you who revere my name, the sun of righteousness
will rise with healing in its wings. And you will go out and leap
like calves released from the stall

God not only intends for us to be healed, but to gain back more than we lost.
