Mark 2:10-11

But so that you may know that the Son of Man has the authority and power on earth to forgive sins-He said to the paralyzed man, I say to you, get up, pick up your mat and go home.  

An obstacle to healing in many cases is our belief in whether Jesus can and will heal us.  We may need to renew our minds to see healing, but our spirits can, and as we renew the mind to the Word, the healing comes.  Speak the Word against the obstacles the devil tries to put in life.  David didn’t run into the battel with Goliath silent.
