Albert Barnes on Matthew 24:44

Be ye also ready. Lk 21:36 says, that he charged them to pray always, that they might be accounted worthy to escape those things--the judgments coming upon the wicked--and to stand before the Son of man--i. e. to stand there approved by him, or admitted to his favour. He also charged them Lk 21:34 to take heed, and not to suffer their hearts to be overcharged with surfeiting, or too much eating, or drunkenness, or the cares of this life, lest that day should come upon them unawares; things improper if there were no judgment-- peculiarly mad and wicked when the judgment is near.
