Charles H. Spurgeon on Psalms 35:21

Yet, O ye saints, divulge not these things to wicked men; whisper them softly one to another, with fear and trembling, lest some profane wretch or other overhear you, and take that for encouragement that was only meant for caution. What is more common than for the vilest sinners to plead for their excuse, or warrant rather, the foul miscarriages of God's dearest saints? Thus the drunkard looks upon holy Noah as a pot-companion, whereby he discovers his nakedness in a worse sense than ever Cham did; and thus the unclean sensualist quotes David, and calls him in to be the patron of his debauchery. Certainly, if there be any grief that can overcast the perfect joys of the saints in heaven, it is that their names and examples should, to the great dishonour of God, be produced by wicked and sinful men, to countenance their grossest sins and wickednesses. But let such know, that God hath set up these in his church to be monuments of his mercy, to declare to humble and penitent sinners how great sins he can pardon; yet if any hereupon imbolden themselves in sin, instead of being set up as monuments of mercy, God will set them up as pillars of salt. —Ezekiel Hopkins (Bishop).
