Romans 12

And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God. v.2

Read chapter 12
How do you renew your mind?  So easily are our minds are distracted and consumed by the things in this world, we can not live on this earth and not be bombarded by its influence.  It takes discipline to not conform.  This world we live in has many beliefs that are contrary to the word of God.  Even the common thoughts in the religious world today are corrupt.  Where we indulge our mind is what we will conform to.  For example porn is everywhere and is a "normal" thing among most men (and women), so does that mean it's ok?  Well here is where we can apply this verse as a believer, to be diligent and disciplined with our mind and thoughts so that we may be transformed and prove God's perfect will. The believer is not to be apart of the flow of this world, rather to be transformed into the way of Christ.  The battle is in the mind.  Transformed thinking results in transformed actions.  Even the lyrics of music result in what we believe, think and do, whether the words are good or bad.  Following the ways of God may seem contrary to this world, but ultimately proves good and acceptable and understanding God's perfect will.
What do you fill your mind with?  How will you take action to renew your mind this week? How have you seen proven God's way better than the world's way?
