'Ministering' in the Bible

Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints.

For as touching the ministering to the saints, it is superfluous for me to write to you:

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.

Are they [self-proclaimed] servants of Christ?—I am speaking as if I were out of my mind—I am more so [for I exceed them]; with far more labors, with far more imprisonments, beaten times without number, and often in danger of death.
