False teachers are hell's greatest enrichers. Non acerba, sed blanda, Not bitter, but flattering words do all the mischief, said Valerian, the Roman emperor. And the same hard measure had our Lord Jesus from the Scribes and Pharisees, who laboured as for life to build their own credit upon the ruins of his reputation. He that willingly takes from my good name, unwillingly adds to my reward. These are Satan's great benefactors, and such as divine justice will hang up in hell as the greatest malefactors, if the physician of souls does not prevent it.
False teachers are nice in the lesser things of the law, and as negligent in the greater.
The earth groans to bear them, and hell is fitted for them, Matt. Many in these days are bewitched and deceived, viz. They busy themselves most about men's heads. But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction. That they may the better pick your purse, they will hold forth such principles as are very indulgent to the flesh.
