My friend, "Joe", was telling me about a disgruntled woman who recently left his church. (Aside - if there is disgruntled, is there such a thing as gruntled?) "Jane" has been critical of Joe from the time he arrived. The music isn't right. The drums are too loud. Her husband should have been asked to chair a committee. On and on.
When asked by one of the church elders why she was leaving to attend a church in another nearby town (the preaching there isn't any better, by the way), she told him, "I'm not getting anything from Joe's sermons. They just aren't deep enough." This mature elder responded with one of the best answers I think I've ever heard. "Jane, I would hope they're not deep enough for you. You've been a Christian for nearly sixty years. I would hope that, by now, you're mature enough that Joe's preaching isn't nearly deep enough. If its deep enough for you, then he's over the heads of all the new believers we're seeing in our church right now."
God bless that elder and God bless Joe. And while He's at it, God bless Jane and her new preacher. He's gonna need it.
