2:12-18 We must be diligent in the use of all the means which lead to our salvation, persevering therein to the end. With great care, lest, with all our advantages, we should come short. Work out your salvation, for it is God who worketh in you. This encourages us to do our utmost, because our labour shall not be in vain: we must still depend on the grace of God. The working of God's grace in us, is to quicken and engage our endeavours. God's good-will to us, is the cause of his good work in us. Do your duty without murmurings. Do it, and do not find fault with it. Mind your work, and do not quarrel with it. By peaceableness; give no just occasion of offence. The children of God should differ from the sons of men. The more perverse others are, the more careful we should be to keep ourselves blameless and harmless. The doctrine and example of consistent believers will enlighten others, and direct their way to Christ and holiness, even as the light-house warns mariners to avoid rocks, and directs their course into the harbour. Let us try thus to shine. The gospel is the word of life, it makes known to us eternal life through Jesus Christ. Running, denotes earnestness and vigour, continual pressing forward; labouring, denotes constancy, and close application. It is the will of God that believers should be much in rejoicing; and those who are so happy as to have good ministers, have great reason to rejoice with them.

14. murmurings—secret murmurings and complaints against your fellow men arising from selfishness: opposed to the example of Jesus just mentioned (compare the use of the word, Joh 7:12, 13; Ac 6:1; 1Pe 4:9; Jude 16).

disputings—The Greek is translated "doubting" in 1Ti 2:8. But here referring to profitless "disputings" with our fellow men, in relation to whom we are called on to be "blameless and harmless" (Php 2:15): so the Greek is translated, Mr 9:33, 34. These disputings flow from "vain glory" reprobated (Php 2:3); and abounded among the Aristotelian philosophers in Macedon, where Philippi was.
