Interpreting the 'Word' with the modern mind?

Its been a long time since I put in any material on the blog... Sorry guys.
Today I wanted to talk about how we as Christians interpret the scriptures. The aim of course is to develop ourselves as proof producers of the word instead of just 'evangelising' by knocking doors.

Was in a seminar last week and one of the lessons learnt was that I should strive to interpret the gospel or the scriptures with the modern mind. That got me thinking; are we as Christians bringing or applying the gospel in our daily lives. Are our stock brokers discovering any intelligence and thereby using it in the daily application of stock trading for us? Are our bankers, doctors, consultants etc doing the same or are we just like any other person, working from eight (nine) to five and waiting for a salary? What's the difference between our Christian 'workers' and the 'others'

Looking around, I must admit that I dont see enough of Christians practising our so-called Christianity like this. I see alot of other ways though.

What do you think? Am I right in thinking that we as Christians should offer something 'extra' and that extra is what should make us different from people that are not in covenant with God?
