Body and building metaphor both speak meaningful to me. in Paul different metaphors, human body metaphor “A living Sacrifice” speaks because that accounts for the purity of body by proper worship God with faith. In metaphor Roman 12: 1-2, “Do not conform to the pattern of this world but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing, and perfect will” (NIV Cultural Backgrounds Study Bible, p.6680). So, one can sacrifices by doing always good thing and remove all bad indeed to make purity to God. God asked His people to repent and follow His command with faith. That how anyone can please Lord and have blessed life.
