“Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, [a] acceptable to God, which is your [b] spiritual service of worship. And do not be conformed to this [c] world, but be transformed by the renewing of your mind, so that you may [d] prove what the will of God is, that which is good and [e] acceptable and perfect.” (NASB) Romans 12:1-2
A renewed mind is about a mind makeover where you have been thinking one way and recognize you need to change. Change what you fix your attention on; what you think will affect everything you do in life. Proverbs 23:7a says, “For as he [a] thinks within himself, so he is. (NASB)”
“So here’s what I want you to do, God helping you: Take your everyday, ordinary life — your sleeping, eating, going-to-work, and walking-around life — and place it before God as an offering. Embracing what God does for you is the best thing you can do for him. Don’t become so well adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out. Readily recognize what He wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.” Romans 12:1-2 (The Message Bible)
