14 “You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. 16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.

9 But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.

A Living Sacrifice

12:1 I appeal to you therefore, brothers, [1] by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. [2] 2 Do not be conformed to this world, [3] but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. [4]
