² Do not be conformed to this world (this age), [fashioned after and adapted to its external, superficial customs], but be transformed (changed) by the [entire] renewal of your mind [by its new ideals and its new attitude], so that you may prove [for yourselves] what is the good and acceptable and perfect will of God, even the thing which is good and acceptable and perfect [in His sight for you].

¹⁵ Practice and cultivate and meditate upon these duties; throw yourself wholly into them [as your ministry], so that your progress may be evident to everybody.
