John 8:23 - Matthew Poole's English Annotations on the Holy Bible

Ye are not only of an earthly extraction, creatures of the earth, not descended from heaven, as I am; but also of earthly spirits and principles; you savour nothing that is sublime and spiritual, and therefore you do not understand me. I tell you, I am not of this world; my original is not from it, nor am I to determine my being in it. I shall die, but I shall rise again from the dead, and ascend into heaven, where you cannot come. Still our Saviour asserts his Divine nature; and the stress of all, he saith, lieth there; their unbelief of which was the cause of all their disputings and errors. He had given them the greatest evidence of it imaginable in the works which he had done in their sight, which were not only above the power of nature, but such as God had never authorized, or enabled any creature to do; yet they, being destitute of supernatural grace, did not believe in him. And they were inexcusable, because that grace was denied them for their wilful corruption and wickedness, which they might have avoided by the use of that common grace which was not denied them.
