This is not to say that our faith shouldn't be evidenced by our works. The point is not to be focused on impressing or influencing the minds of others about their opinion of you. We serve only one master, so His is the only opinion we should care about.
I don't HAVE a soul- I AM a soul- that has a body for the time being. The difference is enormous. Actually taking this view to heart changes the way you view yourself & every other person you interact with. Try it.
