Readings for Celebrating Advent

12 I beseech you therefore, brethren, by the mercies of God, to present your bodies a living sacrifice, holy, ^[a]acceptable to God, which is your ^[b]spiritual ^[c]service. ² And be not fashioned according to this ^[d]world: but be ye transformed by the renewing of your mind, that ye may prove what is ^[e]the good and ^[f]acceptable and perfect will of God.
