With that introduction, I shall proceed at once to the text. The "sleep" of the text is an evil to be avoided. In the second place, the word "therefore" is employed to show us that there are certain reasons for the avoiding of this sleep. And since the apostle speaks of this sleep with sorrow, it is to teach us that there are some, whom he calls "others," over whom it is our business to lament, because they sleep, and do not watch, and are not sober.
