God has done everything in the work of salvation. We only know Him by His grace.
God has also done everything that we, His people, need in order to live in the manner He desires and expects. Far too often Christians act as if God has left some things out when it comes to the life of the church. This is when the trouble begins. They decide to invent new things that they think will benefit the body. Simply put, they are wrong. God neither needs nor asks for our creativity. It's fine to be creative in other aspects of life, but as it relates to the church it is unnecessary. By giving us the Holy Spirit and the Bible, God has done all that needs to be done. The Holy Spirit empowers and convicts us. The Bible instructs us. This is all we need.
I tire of hearing well-intentioned Christians speak about all the new things their churches are doing. Instead, what they ought to be doing is looking in scripture to see where they are and are not following the model God has given to us. If you look at almost any institutional church you will find a long laundry list of things that have absolutely no Biblical basis. These churches routinely spend large portions of their budgets on all sorts of stuff that, quite frankly, God doesn't care about.
If you read this blog, then you are likely convinced that what we see of the church in scripture is far more than descriptive. Rather, it is prescriptive. The institution fails to see this, much to its detriment. Since we recognize the authoritative nature of the Bible in church life, it's our responsibility to look at self. Are we obeying that model? Are we following it? Or, are we sort of playing around with it, picking and choosing what we like and don't like? It's simple and quite easy to point the finger at all the ways institutional churches are failing. More difficult is looking in the mirror to see where we are being disobedient.
God has given us all we need. I challenge you to take a hard look to see where you may be falling short. It can be a painful process, but it is utterly worthwhile.
