Luke 17:7-10 "Will any one of you who has a servant plowing or keeping sheep say to him when he has come in from the field, 'Come at once and recline at table'? Will he not rather say to him, 'Prepare supper for me and dress properly, and serve me while I eat and drink, and afterward you will eat and drink'? Does he thank the servant because he did what was commanded? So you also, when you have done all that you were commanded say, 'We are unworthy servants, we have only done what was our duty.'"
Recently, I have been privileged to carry some new responsibilities and in the midst of these opportunities I can feel my heart occasionally reeling inward. Although service is being rendered it can often be rendered, not in service to the King, but in service to the servant - me. Or when I have served with supposed great intentions for the King my heart yearns for prestige, comfort, or approval from others. My heart seeks contentment in things I have done and consequently causes discontentment with the King and what he has done on my behalf. I can't serve two masters.
And then I am reminded that my approval is Jesus, my prestige is Jesus, my comfort is Jesus... all that I am and all that I have to feel good about myself is Jesus.
A heart that fails to sense afresh its unworthiness is a heart that has become discontent with the person and work of the King. It's truly wonderful to be spent as an unworthy servant, in service to, the King.
