Why have we come?

In Hebrews 10:7 an old testament verse from PSalms 40 is repeated...I have come, in the volume of the book it is written, to do Your will oh God." If Jesus came to only do the will of His father in heaven, which He says in yet another place, why then have we come?
What is our purpose here. If His was to do the will of God, isn't that at least our reason for being here as well? If our whole lives are not made up with the passion of doing His will and His will alone, what are our passions? WHat does drive us? The things of this world which are passing away? i hope not, and that's what I'm tempted with, to be driven with, and if I give into them, that's what then drives me.
So what drives us? A passion for cars, a passion for food, unforgiveness, a root of bitterness, what lusts hang us up, and how is that effecting our relationship with Christ?
"Lord we Love you, take us over, again, make us new, again, bring us closer, let us realize again why we were made, for Your precious purposes, "To do Your will oh God."
In Jesus Name, amen.
