3. Let nothing be done--The italicized words are not in the Greek. Perhaps the ellipsis had better be supplied from the Greek (Php 2:2), "Thinking nothing in the way of strife" (or rather, "factious intrigue," "self-seeking," see on Php 1:16). It is the thought which characterizes the action as good or bad before God.
      lowliness of mind--The direct relation of this grace is to God alone; it is the sense of dependence of the creature on the Creator as such, and it places all created beings in this respect on a level. The man "lowly of mind" as to his spiritual life is independent of men, and free from all slavish feeling, while sensible of his continual dependence on God. Still it INDIRECTLY affects his behavior toward his fellow men; for, conscious of his entire dependence on God for all his abilities, even as they are dependent on God for theirs, he will not pride himself on his abilities, or exalt self in his conduct toward others (Eph 4:2; Col 3:12) [NEANDER].
      let each esteem--Translate as Greek, "esteeming each other superior to yourselves." Instead of fixing your eyes on those points in which you excel, fix them on those in which your neighbor excels you: this is true "humility."
