How does the concept of spiritual sacrifices apply to Christians today?

In the New Testament, spiritual sacrifices are presented as the appropriate response to God's grace and mercy. Romans 12:1 encourages believers to present their bodies as living sacrifices, holy and acceptable to God, which is our spiritual worship. This means that everything we do should be an act of worship—serving others, loving our neighbors, and proclaiming the gospel manifest the spiritual sacrifices God desires from His people. Unlike the physical sacrifices of the Old Covenant, spiritual sacrifices arise from a heart transformed by grace, aimed at glorifying God in all aspects of life.
