What does it mean to be a modern day Christian?

I was just wondering...what does a modern day Christian look like? Are the teachings of Jesus and laws (not to be legalistic) of the OT important to adhere to, or does God change with the times, evolving His image to conform to the humanism of our culture?

Well, I guess you pretty much know what I think. But I want to know what you think, so chime in on this. Don't be skared.

Can't wait,
