I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. Roman’s 12:1-2 ESV

Paul appeals to us to offer to God daily, our will, our choices, and desires as an act of worship. Then, he promises that by following this new way of thinking about life that we will gradually be able to make out our surroundings as the fog lifts (discern). Then we will see clearly what is good in God’s eyes: what is acceptable to Him and how He would have us take the next step towards becoming perfect like Christ.
