I have been using Oswald Chambers' devotional My Utmost for His Highest for many years, and I'm fairly confident that a number of our Pointificators could say the same. The entry for February 24 has struck me with both its depth and beauty. Here's an excerpt and the link to the full entry:

When the Spirit of God has shed abroad the love of God in our hearts, we begin deliberately to identify ourselves with Jesus Christ's interests in other people, and Jesus is interested in every kind of man there is. We have no right in Christian work to be guided by our affinities; this is one of the biggest tests of our relationship to Jesus Christ. The delight of sacrifice is that I lay down my life for my Friend ... for Him and His interests in other people, not for a cause.... If we are abandoned to Jesus, we have no ends of our own to serve. 

(Mark Earley is also talking about Chambers today, in his BreakPoint commentary.)
