Who died for us. — Not a mere pious recollection of a fact which has nothing to do with the context, but an account of the way by which Christ made it possible for us to set about earning salvation. What a blessed privilege a Christian’s life of labour must be, if it alone — to say nothing of the “salvation” at the end — cost such a price!
Whether we wake or sleep. — The mention of Christ’s death at once brings back the recollection of the Advent and the questions concerning the dead in their relation to it. The words “wake or sleep” seem distinctly suggested by the metaphor used from 1 Thessalonians 5:2 to 1 Thessalonians 5:8, being different in the Greek from the terms used in 1 Thessalonians 4, but abruptly take a much altered meaning. They here, no doubt, signify “life and death:” — “Let us arm ourselves with a brave hope of our salvation, for it will be against God’s will if we should perish: He means us to save ourselves by union with Him who put an end to death for us by dying, and made all who wait for His coming to live, whether they be in the world’s sense dead or alive.”
We should live. — In sharp contrast with “who died for us.” Christ’s dying destroyed the power of death (Hebrews 2:14); henceforth it is only a matter of being awake or asleep; those who sleep quite as truly live, and live with Him, as we who wake (see Luke 20:38; and compare the more developed passage in Romans 14:8). The word “together” (as the Greek clearly shows) must be separated from the “with;” rather, “we should live with Him together,” i.e., we quick, and our brethren the dead; for St. Paul has entirely reverted from the effect of the Advent-doctrine upon Christian life to the subject of the last chapter — the equality of the two classes at Christ’s coming. Bengel, thinking that St. Paul is still applying himself to the discussion of the date of the Advent (which in fact was scarcely raised), tries to make out the meaning, “That we should there and then live with Him.”
