To be a disciple of Jesus Christ. Mr. Oswald Chambers daily convicts and stirs my heart in his rich and meaningful devotional called "My Utmost For His Highest".
Here's something from today that I particularly found great:
"Discipleshiop is built entirely on the supernatural
grace of God.... We do not need the grace of God to stand crises, human nature and pride are sufficient, we can face the strain magnificently; but
it does require the supernatural grace of God to live twenty four hours in every day as a saint, to go through drudgery as a disciple, to live an ordinary, unobserved, ignored existence as a disciple of Jesus... We have to be exceptional in the ordinary things, to be holy in mean streets, among mean people, and this is not learned in five minutes."
