1. Offer our bodies as living sacrifices (1,2)
What should we do in view of God's great mercy on us? We should offer our bodies as living sacrifices. This is our true worship. God sacrificed His Son for us so that we could be saved and not condemned. In response to this, we should do no less than offer ourselves to Him as living sacrifices. We should commit our hearts and lives to God. It's not enough to go to church on Sunday and be holy for one day. We should live God-centered lives each day. We should renew our minds and not conform to the sinful ways of this world. Only then can we know what God's pleasing and perfect will is for us.
2. Serving Christ with humbleness (3-8)
Each of us, all together, form the body of Christ. To each of us, God has given certain gifts. To some, He has given the gift of teaching. To others, He has given gifts of prophesying, encouraging, leadership, or some other gift. We should be thankful for our gifts, but not let them make us proud. We should pray to recognize our God-given gifts and to use them to humbly serve the body of Christ.
