'Service' in the Bible

For if the ministry that brings condemnation [the old covenant, the Law] has glory, how much more does glory overflow in the ministry that brings righteousness [the new covenant which declares believers free of guilt and sets them apart for God’s special purpose]!

As for Titus, he is my partner and fellow worker in your service; and as for the [other two] brothers, they are [special] messengers of the churches, a glory and credit to Christ.

For the ministry of this service (offering) is not only supplying the needs of the saints (God’s people), but is also overflowing through many expressions of thanksgiving to God.
