Hopefully making theology simpler to understand! (2 Corinthians 1:12)

I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.

Romans 12:1, ESV

We are not our own, bought with the blood of Christ. We ought to be laying our lives down to serve others in the love and Name of Christ.
