Let me share with you something from another forum where David and I were recently discussing the NLT with someone. Compare Romans 12:2

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

NKJV: 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.

NASB: 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.

RSV: Do not be conformed to this world but be transformed by the renewal of your mind, that you may prove what is the will of God, what is good and acceptable and perfect.

NIV: Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.

ESV: 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.

ISV: Do not be conformed to this world, but continually be transformed by the renewing of your minds so that you may be able to determine what God’s will is—what is proper, pleasing, and perfect.

YLT: and be not conformed to this age, but be transformed by the renewing of your mind, for your proving what is the will of God—the good, and acceptable, and perfect.

NLT: Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect.

Note that in every translation here (certainly not exhaustive of all translations) EXCEPT the NLT, the "transformation" in this verse is rendered as a command -- something that we must do. The NLT changes the thought to something that God does to us, removing man's responsibility and need to act.
