Matthew 13:58 AMPCAnd He did not do many works of power there, because of their unbelief (their lack of faith in the divine mission of Jesus).Matthew 17:15-20 KJVLord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water. [16] And I brought him to thy disciples, and they could not cure him. [17] Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me. [18] And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour. [19] Then came the disciples to Jesus apart, and said, Why could not we cast him out? [20] And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
