Mark 1:34

And Jesus healed many who were suffering with various diseases; and He drove out many demons, but would not allow the demons to speak, because they knew Him (recognizing Him as the son of God). 

Healing is still alive and real today.  Our faith and knowledge of the word of God are what removes any barriers of doubt and unbelief.  Our confession of the word calls for the circumstances to change.  Our belief that Jesus died for our sins and rose again allows us to receive our healing.  Praise the Lord.
