20 For we either hide away our sin, cloaking it over in the depth of our soul, like some festering and malignant disease, as if by escaping the notice of men we could escape the mighty eye of God and justice. Or else we allege excuses in our sins, by devising pleas in defence of our falls, or tightly closing our ears, like the deaf adder that stops her ears, we are obstinate in refusing to hear the voice of the charmer, and be treated with the medicines of wisdom, by which spiritual sickness is healed.
Or, lastly, those of us who are most daring and self-willed shamelessly brazen out our sin before those who would heal it, marching with bared head, as the saying is, into all kinds of transgression. O what madness, if there be no term more fitting for this state of mind! Those whom we ought to love as our benefactors we keep off, as if they were our enemies, hating those who reprove in the gates, and abhorring the righteous word; and we think that we shall succeed in the war that we are waging against those who are well disposed to us by doing ourselves all the harm we can, like men who imagine they are consuming the flesh of others when they are really fastening upon their own.
