Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man. Watch ye therefore, and pray always - Perhaps we should connect ες παντι καιρῳ, continually, with αγρυπνειτε, watch, as it appears to be the most natural order. Indeed the word continually belongs equally to both watch and pray; and no man is safe, at any time, who does not attend to this advice as literally as possible.
That shall come to pass - That is, the tribulations which are on their way to overwhelm and destroy the Jewish people. These are sufficiently stated in the preceding verses.
To stand before the Son of man - To be acquitted, and to be condemned, are expressed, in Romans 14:4, by standing and falling. Those who were faithful to the grace they had received were not only not destroyed in the destruction of Jerusalem, but became heralds of the grace and mercy of God to the nations. Thus they were counted worthy to stand before the Son of man - to minister salvation in his name.
