Seth Godin says:
"All the evidence I've seen shows that positive thinking and confidence improves performance. In anything"

Experience shows this for me particularly in sport. When I do something good on the sports field, then I get better. When I stuff up, I play badly.

Here's my question. If it's true does that mean God wired us that way? And if he did, are Christians good at it? Or do we fall into negative thinking? I'm particularly thinking in terms of sin and our state before God. For example, why is it that in Romans 3:21-26. Every evangelical Christian picks up verse 23 and memorises it, "For all have sinned and fall short of the glory of God". When the verses immediately preceding and following that verse are actually all about how we are made righteous and justified through faith in Jesus. Yes we are sinful and we deserve death, but it seems to me that Paul is actually encouraging us in our justified and righteous state before God through Jesus. Perhaps that kind of reading of the Bible, might lead to Christians thinking of themselves more positively and therefore they'd rise to the challenge of living for Jesus.
