The Bible makes it clear that self-righteousness is the premier enemy of the Gospel. And there is perhaps no group of people who better embody the sin of self-righteousness in the Bible than the Pharisees. In fact, Jesus reserved his harshest criticisms for them, calling them whitewashed tombs and hypocrites. Surprisingly to some, this demonstrates that unrighteous badness is not the only threat to gospel advancement. Self-righteous goodness is equally toxic....
....it’s always the immoral person that gets the Gospel before the moral person. It’s the prostitute who understands grace; it’s the Pharisee who doesn’t. It’s the unrighteous younger brother who gets it before the self-righteous older brother.
There is, however, another side to self-righteousness that younger-brother types need to be careful of. There’s an equally dangerous form of self-righteousness that plagues the unconventional, the liberal, and the non-religious types. We anti-legalists can become just as guilty of legalism in the opposite direction. What do I mean?
It’s simple: we can become self-righteous against those who are self-righteous.
Many younger evangelicals today are reacting to their parents’ conservative, buttoned-down, rule-keeping flavor of “older brother religion” with a type of liberal, untucked, rule-breaking flavor of “younger brother irreligion” which screams, “That’s right, I know I don’t have it all together and you think you do; I know I’m not good and you think you are. That makes me better than you.” See the irony?
In other words, they’re proud that they’re not self-righteous!There's more at the link!
