Serving the Lord with all humility. 

Whoever desires to become great among you, let him be your servant. And whoever desires to be first among you, let him be your slave—just as the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.If anyone thinks himself to be something, when he is nothing, he deceives himself. § I say, through the grace given to me, to everyone … not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith. § When you have done all those things which you are commanded, say, “We are unprofitable servants. We have done what was our duty to do.”Our boasting is this … we conducted ourselves in the world in simplicity and godly sincerity, not with fleshy wisdom but by the grace of God. § We have this treasure in earthen vessels, that the excellence of the power may be of God and not of us.
