'Cannot' in the Bible

But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised.

You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the table of the Lord and the table of demons.

And the eye cannot say to the hand, “I have no need of you”; or again the head to the feet, “I have no need of you.”

Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable.
