Are you healed by faith?

During healing services or conferences, cries often can be heard such as: ""You must believe! Keep standing in faith! Hold on to it! Claim healing! Stand in your authority!" Initially simple, clear, seemingly Biblical-sounding sentences. On the one hand, stated as a condition for being able to heal, on the other hand, reproachful when healing does not occur. How did Jesus and the disciples deal with people in need of healing? And why in that way? Under what conditions did Jesus heal people? Was it based on faith and/or initiative? Did Jesus ever accuse people of unbelief? Did He confirm faith as the cause of healing? In short, are you healed by faith and are you to blame when that does not work? To find an answer to these questions, each healing situation is examined carefully and systematically.
