C.H. Spurgeons's The Treasury of David
Verse 15. If I say, I will speak thus. It is not always wise to speak one's thoughts; if they remain within, they will only injure ourselves; but once uttered, their mischief may be great. From such a man as the psalmist, the utterance which his discontent suggested would have been a heavy blow and deep discouragement to the whole brotherhood. He dared not, therefore, come to such a resolution, but paused, and would not decide to declare his feelings. It was well, for in his case second thoughts were by far the best.
I should offend against the generation of thy children. I should scandalise them, grieve them, and perhaps cause them to offend also. We ought to look at the consequences of our speech to all others, and especially to the church of God. Woe unto the man by whom offence cometh! Rash, undigested, ill considered speech, is responsible for much of the heart burning and trouble in the churches. Would to God that, like Asaph, men would bridle their tongues. Where we have any suspicion of being wrong, it is better to be silent; it can do no harm to be quiet, and it may do serious damage to spread abroad our hastily formed opinions. To grieve the children of God by appearing to act perfidiously and betray the truth, is a sin so heinous, that if the consciences of heresy mongers were not seared as with a hot iron, they would not be so glib as they are to publish abroad their novelties. Expressions which convey the impression that the Lord acts unjustly or unkindly, especially if they fall from the lips of men of known character and experience, are as dangerous as firebrands among stubble; they are used for blasphemous purposes by the ill disposed; and the timid and trembling are sure to be cast down thereby, and to find reason for yet deeper distress of soul.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 15. I should offend, etc. That is, I do God's church a great deal of injury, which hath always been under afflictions, if I think or say, that all her piety hath been without hope, or her hope without effect. Others understand it to mean, I deceive the generation, viz., I propound a false doctrine unto them, which is apt to seduce them. Others, "behold the generation," etc.; that is to say, notwithstanding all afflictions, it is certain that thou art a Father to the Church only; which is sufficient to make me judge well of these afflictions; I have done ill, and confess I have erred in this my rash judgment. John Diodati.
