'Cannot' in the Bible

But the natural man does not receive the things of the Spirit of God, for they are folly to him; and he cannot know them because they are spiritually discerned;

Ye cannot drink the Lord's cup, and the cup of demons: ye cannot partake of the Lord's table, and of the table of demons.

The eye cannot say to the hand, I have not need of thee; or again, the head to the feet, I have not need of you.

But this I say, brethren, that flesh and blood cannot inherit God's kingdom, nor does corruption inherit incorruptibility.
