And he could there do no mighty work, except that he laid his hands upon a few sick folk, and healed them.
All Commentaries on Mark 6:5 Go To Mark 6
John Cassian
AD 435
In some cases he so richly poured forth the mighty work of healing that the Evangelist was led to exclaim: “He healed all their sick.” But among others the unfathomable depth of Christ’s goodness was so thwarted that it was said: “And Jesus could do there no mighty works because of their unbelief.” So the bounty of God is actually curtailed temporarily according to the receptivity of our faith. So it is said to one: “According to your faith may it be to you,” and to another: “Go your way, and as you have believed so let it be to you,” and to another “Let it be to you according as you will,” and again to another: “Your faith has made you whole.”
