4:31,32 Let all bitterness, etc. These verses enforce sundry duties essential to keeping the unity of the Spirit in the bond of peace (Eph 4:3) plain, everyday duties of life. Those of this verse are negative; those in Eph 4:32 are positive.
4:31 Let all bitterness - The height of settled anger, opposite to kindness, ver.32. And wrath - Lasting displeasure toward the ignorant, and them that are out of the way, opposite to tenderheartedness. And anger - The very first risings of disgust at those that injure you, opposite to forgiving one another. And clamour - Or bawling. I am not angry, says one; but it is my way to speak so. Then unlearn that way: it is the way to hell. And evil speaking - Be it in ever so mild and soft a tone, or with ever such professions of kindness. Here is a beautiful retrogradation, beginning with the highest, and descending to the lowest, degree of the want of love.
4:29-32 Filthy words proceed from corruption in the speaker, and they corrupt the minds and manners of those who hear them: Christians should beware of all such discourse. It is the duty of Christians to seek, by the blessing of God, to bring persons to think seriously, and to encourage and warn believers by their conversation. Be ye kind one to another. This sets forth the principle of love in the heart, and the outward expression of it, in a humble, courteous behaviour. Mark how God's forgiveness causes us to forgive. God forgives us, though we had no cause to sin against him. We must forgive, as he has forgiven us. All lying, and corrupt communications, that stir up evil desires and lusts, grieve the Spirit of God. Corrupt passions of bitterness, wrath, anger, clamour, evil-speaking, and malice, grieve the Holy Spirit. Provoke not the holy, blessed Spirit of God to withdraw his presence and his gracious influences. The body will be redeemed from the power of the grave at the resurrection day. Wherever that blessed Spirit dwells as a Sanctifier, he is the earnest of all the joys and glories of that redemption day; and we should be undone, should God take away his Holy Spirit from us.
