You do not deny things the way they are. You call them the way you WANT THEM TO BE.
Speak out the answer ... which is your confession of God's Word. Don't talk your problems which are any of the devil's works in your life. Declare to yourself what God's Word reveals about you, regardless of your circumstances or your feelings.
God uses spiritual forces not seen by our physical eyes to bring the things that you see in the natural to nothing. This is the principle stated in Romans 4:17 which tells us "to call (or speak out of our mouth) those things that are not as though they were".
So call in your healing which has not yet manifested in your physical body. Keep calling yourself HEALED until your body IS HEALED! In this, you are establishing what God has said to be true concerning healing, even though it's not yet a reality in your body.
You do not deny the sickness ... you just deny ITS RIGHT to exist in YOUR body!
Other situations in your life are changed in this way also ... healing is only one of them.
