The Romans 12:2 Change

"And fashion not yourselves like unto this world, but be ye changed by the renewing of your mind, that ye may prove what that good, and acceptable and perfect will of God is." (Romans 12:2, GNV)

Some thoughts on the passage:

This command for the follower of Christ is so simple - yet very radical at the same time.  It is "simple" in the sense that a renewed mind will automatically think differently than a not-renewed mind...so this should work to guide the actions.  However, it is "radical" in the sense that actions coming from a renewed mind, will necessarily clash and conflict with the thinking and actions of the "world" (i.e. the thinking and actions of those people whose minds are not renewed).  So, to "this world" the thinking and actions of the follower of Christ will be radical and strange.  No, not because of different clothes, hairstyle, or speech pattern. These things may indeed change with the new birth - but in many cases they won't and don't need to.  Instead, "...be ye changed" has to refer to the fact that the true follower of Christ will be characterized by trustworthiness, integrity, and unflinching adherence to truth - even when it would seem to not be in his best interest.  A Christian however must be committed to such changes - and indeed make it a lifestyle - because his Master is the very definition and embodiment of Truth (John 14.6) - and Satan conversely is described as "the father of lies." (John 8:44)

Don't misunderstand me.  Christians are not universally trustworthy, full-of-integrity, and honest.  There is not one of us who is! However, this is what we should strive for (by God's grace) and it is what our lives should be characterized by.  May God grant both me and you the renewed mind and the boldness to be different - to be not conformed to the world.
