"Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship. And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect," (Romans 12:1, 2).
* On the basis of his appeal to present our bodies a living sacrifice, the apostle Paul then gives a negative and a positive command--- do not be conformed to this world, but be transformed. The believer who walks in holiness will not let the world system squeeze him into its mold. But rather, he will be willing to stand totally alone, if necessary, as an unashamed rebuke to the worldliness around him.
* Paul presents a three-fold progression in this passage: we are to present ourselves a living sacrifice, refuse conformity with the world, and prove the good and acceptable and perfect will of God. With hearts completely committed to our Lord, we are to refuse the world's continual overtures to compromise a life of holiness. Determined to gain and maintain purity, deafened to the world's wooing, we are to be living proof that the Lord God's will is good, acceptable, and perfect.
