"The very hint of holiness works up such a strong opposition inside the person that it causes him to vomit out the gall and bitterness of his spirit.
Some men are so far from being holy themselves that they ridicule those who are. These think the breastplate of righteousness is so foolish that they laughingly point to the saint who wears it in his daily behavior: "Look! There goes a holy brother, one of the pure ones!" But their mocking language does more than scorn the saint's holiness-- it betrays the wickedness of their own hard hearts.
A further degree of ungodliness appears in mocking the holiness of another person rather than only harboring un-holiness in oneself. How desperately wicked is that man who not only refuses to partake in the divine nature himself but cannot bear the sight of others choosing to follow the holiness of Christ. The very hint of holiness works up such a strong opposition inside the person that it causes him to vomit out the gall and bitterness of his spirit against it.
God's Spirit reserves the chair for this kind of sinner and seats him above all his brethren in iniquity. "Blessed is the man that walks not in the counsel of the ungodly, nor stands in the way of sinners, nor sits in the seat of the scornful Psalm 1:1. In this case the scorner is set as chairman at the counsel-table of sinners.
Some read the word scornful as "rhetorical mockers," for there is indeed a devilish cleverness in some of these jeerers. Such scorners take pride in polishing the darts they shoot against saints. The Septuagint translates the phrase as "the chair of the pestilent ones." As the plaque is the most deadly of diseases, so is the spirit of scorning among sins. Very few recover from this sin, for the Bible speaks of sinners almost synonymously with the dead. God warns us not to waste our healing balm of reproof-- "reprove not a scorner, lest he hate you, Proverbs 9:8. All we can do is write "Lord, have mercy" on his door-- pray for him, but do not try to reason with him.”Quoted material from, ”The Christian in Complete Armour Daily Readings in Spiritual Warfare” by Gurnall and James S Bell. http://www.moodypublishers.com/pub_productDetail.aspx?id=41823&pid=53617
