Matthew 13:58

Because of their unbelief.

Unbelief

An empty vessel capable of holding water, if tightly corked, none can enter it, though water is poured upon it in great abundance; nay, it may be thrown into the sea, and still remain empty. So it is with our hearts; unbelief closes them, so that the water of life cannot fill them, however abundantly it may be poured upon and around us. Could not do many mighty works, etc. Unbelief hinders grace. This sin not only locks up the heart of a sinner, but also binds up the hands of a Saviour. (Burkitt.)

The imperfection of the religion of modern society has its root in the obscure perception of Divine truth. If is only a clear-sighted faith which can grasp the truths of revealed religion, and show to us the relation in which we stand to God. If it does not bring into clear view the obligations and duties which it imposes, and the privileges and graces which it imparts, the life of holiness and devotion will not be seen …. We may trace our imperfect Christian characters, our defective morality, and our almost godless civilization, to a want of faith in our Lord’s doctrines and in His view of life, and our relations to Him and to eternity. It is faith primarily, which will alone bring us into union with Himself, and enable us to see and realize our relations to God as our Creator, Redeemer, and Sanctifier. (R. B. Fairbairn, D. D.)
