'Serving' in the Bible

serving the Lord in all humility, and with tears, and amid trials which came upon me through the plotting of the Jews--

in order fully to equip His people for the work of serving--for the building up of Christ's body--

To them it was revealed that they were serving not themselves but you, when they foretold the very things which have now been openly declared to you by those who, having been taught by the Holy Spirit which had been sent from Heaven, brought you the Good News. Angels long to stoop and look into these things.
