Luke 21:34

But take heed to yourselves, lest haply your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and that day come on you suddenly as a snare: for so shall it come upon all them that dwell upon the face of the earth. But watch ye at every season, making supplication, that ye may prevail to escape all these things that shall come to pass, and to stand before the Son of man.

Take heed to yourselves ... means that men should give more attention to their own spiritual condition than to such questions as the apostles just raised. The vital thing that concerns every person ever born is his relationship to God in Christ; and, as that is the practical concern of greatest importance, Jesus concluded this teaching with this appeal for patient, godly living on the part of his followers.

With surfeiting, drunkenness, and cares of this life ... Ash observed that the word for "surfeiting" "refers to the nausea following a debauch and is used only here in the New Testament."[37] It is translated "dissipation" in RSV, Phillips, and New English Bible. It is noteworthy that "cares of this life" appear here as equally detrimental in some as gross sins are in others.

Suddenly as a snare ... Jesus here stated that the Second Coming will thus come upon "all" that dwell on the face of "all the earth." Thus, none shall expect him at the time of his coming, which appears to give a negative answer to the question he propounded in Luke 18:8.

Watch ye, that ye may escape ... In the TYPE of the final event, the Christians escaped the siege through heeding Jesus' words; the admonition here is that if his disciples watch they shall escape the disasters accompanying the ANTI-TYPE. There is reference to this escape in 1 Thessalonians 4:16-18.

To stand before the Son of man ... These words foretell of glorious majesty pertaining to Jesus Christ in the final judgment. The disciples were either standing or sitting with Jesus when these words were uttered, and they found no discomfort whatever in his presence; but the scene here transferred to the Great Assize, "when the great and terrible day of the Lord has come, and who shall be able to stand!" (2 Corinthians 5:10; Revelation 6:17).
