What does the Bible say about ministry and service?

In Romans 12, the Apostle Paul clearly teaches that the various gifts of ministry are given not for self-serving purposes, but as loving responses to the work of Christ. He exhorts believers to present their bodies as living sacrifices, a reasonable service that reflects Christ's own ministry. This includes acts of love and service towards one another, which aligns with believing that we do not earn salvation through works, but rather, our works are a reaction to the grace we have received in Christ.
