Here is a sample...
"Now that takes me right in to my final thought. Going to church is like joining a gym. If you just show up from time to time your belly won’t shrink and your abs won’t grow. To tell the truth, I don’t even know what abs are, but two infomercials later and the word is stuck in my noggin. My point is that your heart has to be in it. I have never understood this notion of “adherent.” Do you have those at Grace? I think you should get rid of them if you do. As best I understand that big word, it means something like: “not willing to fully commit.” Now, I know I just stepped on a few tender feet, but hear me out. I think (and Mrs. Walter agrees) that you need to do all you can to join whatever church you are attending. Make a promise to be at the meetings and do your best to love the saints. Why would you not? For the life of me I cannot figure it out. All these great blessings would be yours in abundance.
Now some folks have opened their mouths with all kinds of sophistries about being a member of Christ’s church and that being good enough. If I’ve heard that line once I’ve heard it 37 times. Friend, since I barely know you, let me just write, I think your real problem is with pride. I think the thing that keeps most folks from joining a church is a desire to stay unaccountable and to keep their attendance and service and giving to a minimum.
All I can say to that is that you are robbing yourself. Jesus said it was more blessed to give than to receive and I think you ought to join whatever group of believers you are with to do just that very thing. I realize there may be some doctrinal and other tricky issues to overcome... but a room of full of people that love one another ought to be able to find a creative way to do just that – overcome the obstacles."
