I hit pretty hard on the Biblical teaching concerning local-church involvement here, here, and here, recently. One of the excuses/sad stories you hear is about bad pastors, of which (lamentably) there is no lack. But — as I keep asking — what does that have to do with my responsibility to obey out of faith?
Have you ever thought of this, though? Pastors have all had bad experiences with sheep! Every one of them. Probably, the better pastors have had the worst experiences.
So what if you came to a church because you'd heard there was terrific Biblical preaching and living, real fellowship, and the pastor saw you come in, and he got up, came back, and asked you to leave?
Or what if you came for counsel or direction or instruction or encouragement, and he said he just really didn't feel moved to do that anymore?
What if he said, "You know, I've had really bad experiences with people who come to church"?
What if he said, "I had this one couple who were part of the pulpit committee who persuaded me to move from the east coast to the west coast, and promised they'd never leave. Five weeks later, they didn't like something. They left. That really soured me on people."
What if he said, "I led this guy to Christ once, discipled him, baptized him, led him to Christ, introduced him to his wife, performed the wedding — and one year later, I find he led a whisper-campaign to run me out of town on a wave of lies. So I just really don't get involved in people's lives anymore."
I could go on and on. Of course, any Christian who got a truckload like that would retort, "Dude, it's your job. God says it's your job. You need to deal with your issues, and do your job."
...and obeying God isn't your job, too?
Next time, O man/woman, you trot out your Note From Mommy On Why You Are The Exception, imagine the tables turned.
It all boils down to the penultimate question: is someone else's sin ever an excuse for my sin?
Underneath which lies the ultimate question: is God worthy of believing obedience?
