William Burkitt on Matthew 13:58

This sin not only locks up the heart of a sinner, but also binds up the hands of a Saviour. Unbelief obstructed Christ's miraculous works when on earth, and it obstructs his gracious works now in heaven.

Ah! cursed unbelief! which shuts up, O sinner, thy heart, and shuts out thy Saviour, and will effectually shut thee out of heaven, and not only procure damnation, but no damnation like it!

Christ was unable because they were unwilling; his impotency was occasioned by their infidelity; he did not, because he would not; and that he would not, proceeded from a defect in their faith, not from any deficiency in Christ's power; their unbelief bound his hands, and hindered the execution of his power.
