Favorite targets for these people include:
a) Famous Christians (“Did you know that this famous leader once sinned? Gasp!”),
b) Politicians (This doesn't need much explanation; there aren’t many Christians who can say positive things about all three: Trump, Clinton and Obama),
c) Poignant Facebook posts (“Martin Luther is an evil man because some of his followers did bad things!”)
I’m convinced that this is a model given to us by the accuser of the brethren, since these are indeed accusations, and it’s aggressively marketed to us by the secular (and, to a lesser extent, Christian) news media.
When I run across people who have to begin their conversation with criticism or “We need to know both sides of that!” then I’m afraid I make the assumption that this is a person who is more influenced by the news media than by the Spirit of God. (I don’t like assumptions, particularly in myself.)
Our Instruction Book gives us certain standards for our behavior, and for our conversation with each other, standards like “Let your conversation be always full of grace, seasoned with salt.” (Colossians 4:6)
And one of those standards is not fault-finding: Proverbs 11:12 “People without good sense find fault with their neighbors, but those with understanding keep quiet.” & Jude 1:16 “These people are grumblers and faultfinders; they follow their own evil desires; they boast about themselves and flatter others for their own advantage.”
Another of those standards is the solution: fixing our attention on whatsoever is good and right. Philippians 4:8: “Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.”.
Faultfinding is a fundamental failure to meet Scriptural standards, I’m afraid. It’s also something I aggressively discourage in conversations on this page (as I am doing in this post).
Off the record, my motivation for discouraging this is not Scripture: you are responsible for your own response to that standard; that’s not my job.
I speak up because being around that particular work of the enemy (the “accuser of the brethren” Revelation 12:10) is like swimming in a sewer for me: it’s incredibly distasteful, and more importantly, it’s really quite dangerous to my own health.
If you want to find fault with people, living or dead, do it somewhere else. If you to take a crap, don’t use my swimming pool for that purpose.
