New Living Translation
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.
