What does the Bible say about reasonable service?

In Romans 12:1, the Apostle Paul urges believers to present their bodies as living sacrifices, holy and acceptable unto God, stating that this act is their reasonable service. The foundation of this exhortation lies in the profound mercies shown to them by God. Having received such great mercy, believers are compelled to respond with their entire lives dedicated to God's service. This service is not a means to earn favor with God, but a response of gratitude and love for the grace already afforded to them through Christ's sacrifice.
