What extinguishes it? Look at the catalogue of sins that lie side by side with this exhortation of my text! They are all small matters--bitterness, wrath, anger, clamour, evil-speaking, malice, stealing, lying, and the like; very 'homely' transgressions, if I may so say. Yes, and if you pile enough of them upon the spark that is in your hearts you will smother it out. Sin, the wrenching of myself away from the influences, not attending to the whispers and suggestions, being blind to the teaching of the Spirit through the Word and through Providence: these are the things that 'grieve the Holy Spirit of God.'
And so, lastly, we have here--
IV. A Tender Motive, a dissuasive from sin, a persuasive to yielding and to righteousness.
Many a man has been kept from doing wrong things by thinking of a sad pale face sitting at home waiting for him. Many a boy has been kept from youthful transgressions which war against his soul here, on the streets of Manchester, full as they are of temptations, by thinking that it would grieve the poor old mother in her cottage, away down in the country somewhere. We can bring that same motive to bear, with infinitely increased force, in regard to our conduct as Christian people. 'Grieve not the Holy Spirit of God.' A father feels a pang if he sees that his child makes no account of some precious gift that he has bestowed upon him, and leaves it lying about anywhere. A loving friend, standing on the margin of the stream, and calling to his friends in a boat when they are drifting to the rapids, turns away sad if they do not attend to his voice. That Divine Spirit pleads with us, and proffers its gifts to us, and turns away--I was going to use too strong a word, perhaps--sick at heart, not because of wounded authority, but because of wounded love and baffled desire to help, when we, in spite of It, will take our own way, neglect the call that warns us of our peril, and leave untouched the gifts that would have made us safe.
Dear brethren, surely such a dissuasive from evil, and such a persuasive to good, is mightier than all abstractions about duty and conscience and right, and the like. 'Do it rightly' says Paul, 'and you will please Him that hath called you'; leave the evil thing undone, 'and my heart shall be glad, even mine.' You and I can grieve the Christ whose Spirit is given to us. You and I can add something to 'the joy of our Lord.'
