12 I appeal to you therefore, brethren, and beg of you in view of [all] the mercies of God, to make a decisive dedication of your bodies [presenting all your members and faculties] as a living sacrifice, holy (devoted, consecrated) and well pleasing to God, which is your reasonable (rational, intelligent) service and spiritual worship.

³ For by the grace (unmerited favor of God) given to me I warn everyone among you not to estimate and think of himself more highly than he ought [not to have an exaggerated opinion of his own importance], but to rate his ability with sober judgment, each according to the degree of faith apportioned by God to him.

¹⁰ Love one another with brotherly affection [as members of one family], giving precedence and showing honor to one another.

¹⁶ Live in harmony with one another; do not be haughty (snobbish, high-minded, exclusive), but readily adjust yourself to [people, things] and give yourselves to humble tasks. Never overestimate yourself or be wise in your own conceits.^(A)

¹⁸ If possible, as far as it depends on you, live at peace with everyone.
