In his letter to the Christians at Rome, Saint Paul suggested that an ethical life of compassion, service, peace, and justice is the single form of worship that God desires. According to Paul, it is the only form of worship that God deems good, acceptable and perfect.
I appeal to you therefore, brothers and sisters, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewing of your minds, so that you may discern what is the will of God—what is good and acceptable and perfect. (Romans 12:1-2)
Here is how Eugene Patterson paraphrases these two verses:
So here’s what I want you to do, God helping you: Take your everyday, ordinary life—your sleeping, eating, going-to-work, and walking-around life—and place it before God as an offering. Embracing what God does for you is the best thing you can do for him. Don’t become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out. Readily recognize what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.
In an unpublished essay, Dr. Lesly Massey, a Disciple of Christ pastor in Dallas, Texas, quoted Ernst Käsemann (1906-1998), an eminent Lutheran theologian who was a part of the Confessing Church in Germany during the reign of Adolf Hitler. Käsemann, who after World War II spurred a renewed quest to understand the historical Jesus, saw in Romans 12:1 an unequivocal summary of Paul’s view of worship as a follower of Christ.
Christian worship does not consist of what is practiced at sacred sites, at sacred times, and with sacred acts. It is the offering of bodily existence in the otherwise profane sphere, as something constantly demanded. This takes place in daily life, whereby every Christian is simultaneously sacrifice and priest.
