One of the dynamics that seemingly operates among those in the New Calvinist (and many Calvinists) ideological camp is a questioning of one’s salvation experience — Are you actually a Christian, a believer in the person and work of Jesus for your forgiveness of sin, if you are not living that out consistently in your life?
Much more could be said about that dynamic. Nevertheless, it is interesting that this dynamic is not in play when it comes to the pastors and teachers of the Scripture who experience significant moral failures in the ministry! I only need to cite one of the most immediate examples, Matt Chandler.  There are others who illustrate this dynamic and about whom could be asked the same question.
Why is no one asking (and no one is!), including Chandler himself, whether he was a Christian, a genuine believer, all the years of his pulpit ministry? Shouldn’t that question be asked? Should he publicly confess his new faith in Christ through the waters of baptism now that he has “repented” from such sinful practices — a sinful pattern that lasted for an extended period of time?
While preaching to others the truths found in the Scriptures, he himself was sinfully hypocritical and found to be so by those closest to the situation within his local church. That ought to be sufficient reason alone for those who hold to this theological-ideology to call on Chandler to declare that he was not a believer and has since come to Christ as Saviour!
Yes, it is an interesting dynamic within the New Calvinists camp! Calling into question one’s salvation and/or shaking one’s faith in Christ doesn’t seem to operate when it comes to some of the most primary fallen preachers within the movement! They themselves neither claim lostness, nor do other leaders within the ideological movement call out those who, like Chandler, occupy the pulpits while living a duplicitous sinful life.
In contrast, there seems to be little hesitation when it comes to those sitting in the pew, struggling with real-life issues of Christlikeness as they navigate their lives outside of the local church employment.
Is Matt Chandler A Believer In The Person & Work Of Christ?
I have no doubt that he is, but not based on what some pastors are teaching from the pulpits of their local churches! 
- “Humble Calvinism” — A Good Read!
“We Calvinist leave behind a trail of destruction in our churches and families and friendships . . . .
. . . We Calvinist might be the ones who don’t ‘get it’ yet.”
- The same question could be asked of Robert Louis Dabney, an undeniably ardent racist yet a theological luminary.* His writings may be some of the most cited works by men like John Piper, John Mac Arthur, et al. Should we be citing the works of “lost men” like Dabney?
He never repented in the slightest of his ardent racism!
