be ambitious for God

Well I didn't go to church this morning because I'm having a hard time finding a place that I like enough, but I did watch a summit sermon :)  The summit church is pretty awesome and I love their overall vision.  The sermon was on scripture in Philippians and the main point was that we need to be ambitious in life for the right things.  A great point made was-- it is how we respond when our ambitions are disappointed that reveals whether they are godly or selfish ones.  God knows what is best for us in life, and we have to be willing to sacrifice some of our dreams and what we think we deserve for his kingdom.  In all honesty we deserve hell...but God died for us so that we could discover grace through him. I guess I'm trying to work on not complaining and giving my life over to God.  I really need no ones approval in this life..and I want to be content in Christ.
