To Be A Sacrifice

1Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God—this is your spiritual act of worship. 2Do not conform any longer 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.
3For by the grace given me I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the measure of faith God has given you. 4Just as each of us has one body with many members, and these members do not all have the same function, 5so in Christ we who are many form one body, and each member belongs to all the others. 6We have different gifts, according to the grace given us. If a man's gift is prophesying, let him use it in proportion to his faith. 7If it is serving, let him serve; if it is teaching, let him teach; 8if it is encouraging, let him encourage; if it is contributing to the needs of others, let him give generously; if it is leadership, let him govern diligently; if it is showing mercy, let him do it cheerfully.
Love 9Love must be sincere. Hate what is evil; cling to what is good. 10Be devoted to one another in brotherly love. Honor one another above yourselves. 11Never be lacking in zeal, but keep your spiritual fervor, serving the Lord.

The world is a place of self-interest and division - not the body of Christ. We are one body that has given up ourselves, denying self for the interest of one another and for Christ. This is the only reasonable act in light of what Christ has done in us.
