“After looking around at them all, he said to the man: ‘Stretch out your hand.’ He did so, and his hand was restored.”
~Luke 6:10

Did Jesus expect his followers to be charismatic faith healers?
Unlike religious faith healers, Jesus’ healings were not characterized by sensationalist drama and were usually rather casual.(Matt. 8:14, 15; Luke 8:43-48; 17:12-19)
The healings were physically visible. Had they been merely psychosomatic healings, the effects would have worn off sooner or later.
For instance, in the case of the man whose hand was paralyzed, Luke the medic says the hand was literally restored.
That is why not even Jesus’ enemies ever denied that the healings were really taking place.
Instead, they planned to kill Jesus (Luke 6:11; John 11:47,48)
Jesus’ healings served the purpose of signaling him as the messiah and savior of mankind. (Heb. 2:3,4)
But after the Christian congregation were established, some would perform “powerful works” in his name without his approval.(Matt. 7:21-23)
Such miracles would no longer be necessary because love was to be the hallmark trait of true Christians.(1 Cor. 12:27–13:2, 8)
His disciples would display that love by spreading the good news of God’s kingdom to everyone. (Matt. 24:14; 28:19,20)
