In today's passage, Paul addresses the Christian's thought life. In order to grow more and more in our Christ-likeness, we are called to have a renewed mind. Romans 12:2 tells us this - the renewal of our minds - is key to true transformation and the ability to discern the will of God. He calls us to think upon and consider those things that are admirable and to avoid that which is not. And then, we are to practice these things - to act - for that is where we find the God of Peace, and that is the place of true rest!
