We are either living sacrifices unto the Lord, or we are sacrificing our lives unto the world, but we cannot do both. One way dedicates life to serving the cause of Christ, while the other dedicates life to serving the cause of self. To whom do you sacrifice? "I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service" (Romans 12:1).
