Ephesians 4:30

And grieve not the Holy Spirit of God,.... Not a believer's own spirit, sanctified by the Holy Ghost, which is grieved by sin; nor the spirit of a good man, that hears our words and sees our actions, and is displeased and troubled at them; but the third person in the Trinity: and this is said of him by an anthropopathy, and supposes something done that is offensive to him; and he may be grieved, not only by unconverted persons, by their stubborn resistance and opposition to the Gospel and means of grace, and by their contempt of his person, office, and grace, but by believers themselves, and who are here spoken to; and which may be done both by their words, lying, angry, and corrupt ones, before cautioned against, Eph 4:25 and by their actions, their behaviour towards God, their conversation in the world, and by their carriage to one another, which is suggested in the following verse: also he may be grieved by their thoughts, their vain and sinful thoughts, and that they are no better employed; and especially when they entertain any undervaluing ones of Jesus Christ, whose glorifier he is; and by the unbelief of their hearts, and by their unmindfulness of the things of the Spirit; and when they disregard the rules, dictates, and advice of the Spirit, and make no use of him: and his being grieved appears by his departure from them; which is to be perceived by the darkness of their souls, the prevailings of corruption, the weakness of grace, and their backwardness to duty: and now there are many reasons why he should not be grieved; as because he is God, and the author of the new birth, the implanter and applier of all grace, and the finisher of it; because he is the saints' comforter, their advocate, helper, and strengthener; and their constant companion, who dwells in them, and will remain in them, until death: and it follows,whereby ye are sealed unto the day of redemption; of the sealing work of the Spirit, See Gill on "Eph 1:13".
