'Incapable' in the Bible

But the natural [unbelieving] man does not accept the things [the teachings and revelations] of the Spirit of God, for they are foolishness [absurd and illogical] to him; and he is incapable of understanding them, because they are spiritually discerned and appreciated, [and he is unqualified to judge spiritual matters].

in a moment, in the twinkling of an eye, at the sounding of the last trumpet; for the trumpet will sound, and the dead will be raised incapable of decay, and *we* shall be changed.
