Lordship

I am purchased with a price. My life is not my own. George Muller said "Do not think to ever overcome your inward corruptions in any degree unless in your weakness you spend much time with the Lord in prayer." I am learning much about what it means to be under the lordship of Jesus Christ.
Luke 17:7 * But which of you, having a servant plowing or feeding cattle, will say unto him by and by, when he is come from the field, Go and sit down to meat?
8 * And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink?
9 * Doth he thank that servant because he did the things that were commanded him? I trow not.
10 * So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
