You might ask the question...is it the God's will for me to be healed?
Yes
John 3:16 (AMP) For God so greatly loved and dearly prized the world that He [even] gave up His only begotten (unique) Son, so that whoever believes in (trusts in, clings to, relies on) Him shall not perish (come to destruction, be lost) but have eternal (everlasting) life.
17 For God did not send the Son into the world in order to judge (to reject, to condemn, to pass sentence on) the world, but that the world might find salvation and be made safe and sound through Him.
-------------------------
It is God's will for us to be healed, Jesus took on our sicknesses, and our sins on himself.
Isaiah 53:5 (KJV) but he was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his stripes we are healed.
----------------------------------------
It is God's will for you to be healed, because of the perfect gift he has given - Jesus Christ.
you have to receive your healing like a free gift by believing God has given it, You've done nothing to earn it, you can't earn it...nobody could. But because of what Jesus has done for us, we were made worthy to receive his promises. He took our place, even though we didn't deserve it. So that we would live forever with him.
when you pray tell God you receive what Jesus has done for you, that you receive his word as truth in your heart. That it is his will for you to live, and be healed.
Even when the devil comes and try to tell you that it is not true, combat those doubts and tell them what God has promised you with the word of God,
Let the word of God become your truth, have faith, all things are possible to those who believe.
