12 Therefore, I appeal to you by the compassions of God, brothers, to present your bodies+ as a living sacrifice, holy+ and acceptable to God, a sacred service with your power of reason.+

5 Really, the objective of this instruction* is love+ out of a clean heart and out of a good conscience and out of faith+ without hypocrisy.

9 holding the sacred secret of the faith with a clean conscience.+

3 And everyone who has this hope in him purifies himself,+ just as that one is pure.
