John 16:18

Still they do not understand what he meant. Who shall hereafter arrogate to man's reason or understanding a power to comprehend spiritual mysteries? Had not the disciples reasonable souls? Will any say they had no mind to understand them? Certainly none can say so. Some lay the fault of the disciples not understanding these things upon the obscurity of our Saviour's phrase, and his parabolical expression of them, others, in their ignorance of our Saviour's resurrection from the dead; others, in their not understanding the circumstance of time: but certainly it is best imputed to the disciples inability to conceive of these things, and the prejudices of their national error concerning the temporal kingdom of the Messias. Let it lie where it will, the weakness of the disciples may be reasonably conceived not to be greater than is incident to the best of men; and if they were so dull of hearing and understanding, we may reasonably conceive that we are not free from the like impotency and infirmity.
