Note: I wrote this 11 years ago, but I still feel the same way. There is no such thing as biblical Lone Ranger Christianity. None of us were meant to figure out this life alone. We need each other, which is why God designed the Church.
Now on to what I wrote back in the day:
I think one of the reasons that community is so important is that it enlarges our view of God. I like to think that each of us carry puzzle pieces of what God is like. Each has a few pieces that reveal a limited aspect of God. When you get to know me, you add more pieces to your puzzle and your view of God gets bigger and clearer. When I get to know you, the same happens for me.
The more people whose lives we invest in, the more pieces and the bigger our view of God becomes and the more the pieces fall into place and connect into more coherent forms.
I truly believe that we grow as believers and our knowledge of God increases only in the context of community, where we share with each other and serve one another in love. There’s no way I can figuire out God on my own, apart from other believers.
There it is. That’s my thought for the day. Hope it helps.
