Church actually take a lot of organising and many of us don't have the time or energy for it. If you volunteer for ministry in essence you've got to commit your life to it, and that means you may have to sacrifice something like a pay check.
That's kind of hard to do if you depend on that paycheck for a living and to pay your bills. So it does seems church is only for rich, retired people. For the average worker, church commitments and socialising are exhausting. I thought Jesus yoke was meant to be easy and the burden light....but in some churches it's the exact opposite.
the Pharisees set the rules without having to lift a finger themselves, and if there's one thing I learned, is there's still a lot of Pharisees in churches, actually it attracts them. I guess thats is the difference between clergymen and laymen, but that distinction is actually not recognised in many churches anymore.
