Jud 1:4 For certain people have crept in unnoticed who long ago were designated for this condemnation, ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ.
I came across the following quote while reading the Hebrews Commentary (Geneva Series) by a Scotsman named John Brown (1784-1858):
A pastoral ministry destitute of vital religion (ie, of not being born again) is one of the most unnatural of all things and one of the deadliest curses which can light on a Christian church; and to the individual himself it is full of eternal hazard. An unregenerate man, after joining a Christian church, is less likely to be converted than he was previously. If he became (subsequently) a student of divinity, the probabilities of final impenitence are greatly multiplied; and if he enters on the function of ministry (ie, becomes a pastor) the hope of his being saved is faint indeed.” (Hints to Students of Divinity, page 27)
There is no harder, greater sinner to be found than the one who puts on a show of Christianity. To have the conscienceless audacity to claim to serve Christ when in fact one’s motive is entirely selfish is the mark of a person who has no fear of God.
And this is a primary reason why I have always said that a “Christian” abuser (reviler, sociopath, etc) never, ever changes. Never repents. Never is broken and humbled by his (or her) sin. To dare come into the holy of holies and offer “strange fire” before God is to invite oneself into hell.
Many men and some women down through the centuries of church history have dared to take on the office of the Christian ministry, preaching to others but never preaching to themselves. God sees it. He knows.
Rom 2:1-3 Therefore you have no excuse, O man, every one of you who judges. For in passing judgment on another you condemn yourself, because you, the judge, practice the very same things. (2) We know that the judgment of God rightly falls on those who practice such things. (3) Do you suppose, O man—you who judge those who practice such things and yet do them yourself—that you will escape the judgment of God?
