Creating God in our image

I realised the other day that many of our problems, both for Christians and people who don't follow Jesus, are caused by not knowing who God is. We effectively model Him in our image. We take our far from perfect humanity and make it a few thousand percent bigger. What we end up with is a large version of ourselves with all the insecurities, the boredom, the impatience etc and this makes it hard to understand what He is like. Since everyone in the world would do this in a different way, we end up with 6 billion versions of God even though He is one.
To understand God, we need to understand His character from first principles, from the Bible. As we read about Him and learn what He is like, we then see ourselves as broken vessels modelled in the image of God but with defects.
Imagine you owned a car worth £50. Busted seats, an engine that burned more oil than petrol and loads of rust. If someone told you that there was a Rolls Royce worth £200,000, you wouldn't imagine an expensive version of the same thing. You wouldn't think that for your money, you get more oil burning, more busted seats and more rust patches. In short you would not create the Rolls Royce in the same image as your cheap car. This would be obviously incorrect and illogical, it would lead to all kinds of strange conclusions about cars. Imagine however if you saw the Rolls Royce or at least had it described to you and then realised that your car was a broken cheap version of the Rolls. This would make much more sense, it would logically make sense and most importantly, it would give the Rolls Royce all the honour and credit for what it actually is.
