Romans 13:11

We are here taught a lesson of sobriety and godliness in ourselves. Our main care must be to look to ourselves. Four things we are here taught, as a Christian's directory for his day's work: when to awake, how to dress ourselves, how to walk, and what provision to make. I. When to awake: Now it is high time to awake (Rom 13:11), to awake out of the sleep of sin (for a sinful condition is a sleeping condition), out of the sleep of carnal security, sloth and negligence, out of the sleep of spiritual death, and out of the sleep of spiritual deadness; both the wise and foolish virgins slumbered and slept, Mat 25:5. We have need to be often excited and stirred up to awake. The word of command to all Christ's disciples is, Watch. "Awake - be concerned about your souls and your eternal interest; take heed of sin, be ready to, and serious in, that which is good, and live in a constant expectation of the coming of our Lord. Considering," 1. "The time we are cast into: Knowing the time. Consider what time of day it is with us, and you will see it is high time to awake. It is gospel time, it is the accepted time, it is working time; it is a time when more is expected than was in the times of that ignorance which God winked at, when people sat in darkness.

And that--rather, "And this [do]" knowing the time, that now it is high time--literally, "the hour has already come." to awake out of sleep--of stupid, fatal indifference to eternal things. for now is our salvation--rather, "the salvation," or simply "salvation." nearer than when we--first believed--This is in the line of all our Lord's teaching, which represents the decisive day of Christ's second appearing as at hand, to keep believers ever in the attitude of wakeful expectancy, but without reference to the chronological nearness or distance of that event.
