There is a sense in which every sin is against the Holy Ghost. Of course, not every such sin is unpardonable, but the tendency of all sin is in that direction, and we are only safe as we avoid the very beginnings of sin. Only as we "walk in the Spirit" are we "free from the law of sin and death" (Romans viii. 2). Therefore, it is infinitely important that we beware of offences against the Spirit, "lest any of you be hardened through the deceitfulness of sin" (Hebrews iii. 13). Grieving the Holy Spirit is a very common and a very sad offence of professing Christians, and it is to this that must be attributed much of the weakness and ignorance and joylessness of so many followers of Christ. And He is grieved, as was my mother, by the unloving speech and spirit of God's children. In his letters to the Ephesians, Paul says, "Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers." And then he adds: "And grieve not the Holy Spirit of God, whereby ye are sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamour, and evil-speaking, be put away from you, with all malice. And be ye kind one to another, tender-hearted, forgiving one another, even as God for Christ's sake hath forgiven you. Be ye therefore followers of God, as dear children; and walk in love, as Christ also hath loved us, and hath given Himself for us" (Eph. iv. 29-v. 2). What does Paul teach us here? That it is not by some huge wickedness, some Judas-like betrayal, some tempting and lying to the Holy Ghost, as did Ananias and Sapphira (Acts v. 1-9), that we grieve Him, but by that which most people count little and unimportant; by talk that corrupts instead of blessing and building up those that hear, by gossip, by bitterness, and uncharitable criticisms and fault-findings. This was the sin of the elder son when the prodigal returned, and it was by this he pierced with grief the kind old father's heart. By getting in a rage, by loud, angry talking and evil-speaking and petty malice, by unkindness and hard-heartedness and an unforgiving spirit, we grieve Him. In a word, by not walking through the world as in our Father's house, and among our neighbours and friends as among His dear children; by not loving tenderly and making kindly sacrifices for one another, He is grieved. And this is not a matter of little importance. It may have sadly momentous consequences.
