You know, I think that there will be a lot of surprises in heaven. One will be who all is there. On prefield ministry we traveled to all different types of churches and with our many other travels, we have seen all kinds of different churches. Even down here in Brasil, the churches are different. I think that we can have church in all different kinds of ways and still get the main point of worshiping God.
But I think that God had a great purpose in creating the church. He did not just create it cause it sounded like a good idea. He desires that we first of all glorify God. We do that so much in the church. But we also do that by following the idea of church in having fellowship with other believers. That fellowship glorifies His Name. One purpose of the church is to heal us when we are broken. We encourage others through difficult times in the church, and then when we go through hard times, we may be encouraged as well. I know people who leave the church when going through hard times personally, but that is the time where in the church they should be encouraged and be rallied around.
There is a lot to say about serving in the church as well. JFK's quote about the country is just as applicable with the church, "It is not what your church can do for you, it is what you can do for your church." We should all be servants in our local church!
