Answer: That we are not our own but belong, body and soul, both in life and death, to God and to our Savior Jesus Christ.
Scripture: Romans 14:7-8 – For none of us lives to himself, and none of us dies to himself. For if we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or whether we die, we are the Lord’s.
