The New Testament teaches that Christians are called to offer “spiritual sacrifices acceptable to God through Jesus Christ” (1 Pet 2:5). These sacrifices express the believer’s priestly service in the Church Age and arise from gratitude rather than obligation. Paul urged believers to “present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship” (Rom 12:1), indicating that consecration of the whole person (mind, body, and will) is a central act of priestly devotion. Moreover, believers are called to continual worship and thanksgiving, to “continually offer up a sacrifice of praise to God, that is, the fruit of lips that give thanks to His name” (Heb 13:15).
