Mark 5:
Luke 6:
Jesus could not or did not do many miracles in his hometown?
Both are true. If they didn't believe, it would not work.
Another illustration happened when Peter saw Jesus walk on the water, Matthew 14:
Power resided in the physical person of Jesus.25 There was a woman who had had a discharge of blood for twelve years, ... 28 she said, “If I touch even his garments, I will be made well.” 29And immediately the flow of blood dried up, and she felt in her body that she was healed of her disease. 30And Jesus, perceiving in himself that power had gone out from him, immediately turned about in the crowd and said, “Who touched my garments?”
Faith could connect with that power.34 And he said to her, “Daughter, your faith has made you well; go in peace, and be healed of your disease.”
Luke 6:
Later, on the other hand, Jesus visited his hometown, Mark 6:19 and the people all tried to touch him, because power was coming from him and healing them all.
A parallel account in Matthew 13:5 he could do no mighty work there, except that he laid his hands on a few sick people and healed them. 6a And he marveled because of their unbelief.
Unbelief was the disconnect with that power. They did not plug into that power.58 he did not do many mighty works there, because of their unbelief.

Another illustration happened when Peter saw Jesus walk on the water, Matthew 14:
Peter had good faith.28 Peter answered him, “Lord, if it is you, command me to come to you on the water.” 29He said, “Come.” So Peter got out of the boat and walked on the water and came to Jesus.
Peter shifted his focus and now his faith was in trouble.30 But when he saw the wind, he was afraid, and beginning to sink he cried out, “Lord, save me.”
31 Jesus immediately reached out his hand and took hold of him, saying to him, “O you of little faith, why did you doubt?”
