why be bummed?

Last night we did this fiesta literature night for some kids from a school. IT didn't really go how we wanted it to, and I didn't really see very much benefit from it all, so I ask God- what was the purpose... I put a lot of time and money into something that was crappy... why?

This is what I read this morning in My Upmost for His Highest by Oswald Chambers

The DESTITUTION OF SERVICE

"Though the more abundantly I love you, the less I be loved."
2 Corinthians 12:15
Natural love expects some return, but Paul says- I do not care whether you love me or not, I am willing to destitute myself completely, not merely for your sakes, but that I may get you to God. "For ye know the grace of our Lord Jesus Christ, that, though He was rich, yet for your sakes He became poor." Pauls idea of service is exactly along that line- I do not care either what extravegence I spend myself, and I will do it gladly. It was a joyful thing to Paul.
The ecclesiastical idea of a servant of God is not Jesus Christ's idea. His idea of a servant of God is that we serve Him by being the servants of other men. Jesus Christ out-socialists the socialists. He says that in His Kingdom he that is greatest shall be the servant of all (and all the Losers get a crown). The real test of the saint is not preaching the gospel, but washing disciples' feet, that is, doing the things that do not count everything in the estimate of God. Paul delighted to spend himself out for God's interest in other people, and he did not care what it cost. We come in with our economical notions- "Suppose God wants me to go there- what about the salary? What about the climate? How shall I be looked after? A man must consider these things." All that is an indication that we are serving God with a saint in his life, viz., not one who proclaims the Gospel merely, but one who becomes broken bread and poured-out wine in the hands of Jesus Christ for other lives.

So long as there is a human being who dies not knowing Jesus Christ I am his debtor to serve him until he does. The mainspring of Pauls service was not for the love of men, but love for Jesus Christ. If we are devoted to the cause of humanity, we shall soon be crushed and broken-hearted, for we shall often meet with more ingratitude from men than we would from a dog; but if our motive is love to God, no ingratitude can hinder us from serving fellow man.
