What are we here for anyway?

My wonderful home fellowship group, as our church likes to call them, is studying Ephesians. Every week someone leads and we discuss a chapter. We just finished 1 and 2. I was struck by some verses in chapter one that had never hit so hard.
"Making known to us the mystery of His will, according to His purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in Him, things in heaven and things on earth." Ephesians 1:9-10

He has made known to us what is the purpose of life! So many of us(humanity) sit and wonder what this life is all about and God has chosen us and told us the mystery. His plan is to unite all things in Him, the plan that He set forth in Christ. I just think that is awesome. Our lives are not meaningless, we don't bring meaning to our lives as some existentialists would say. God chose us to lavish His grace on, to give us wisdom and insight to the mysteries of the world! What an awesome God we serve, for He is great and worthy to be praised. I don't know if this made any sense to anybody else, but it is exciting. We know that in the end God will come through. That the temptations, sins, hurts, and sorrows of this world will end and we will be united in Him.
Sometimes when I read books, hee hee, I look on the last few pages to see if it ends the way I want it to. Like if the girl gets the guy, or the other way around, whatever. If it doesn't end the way I want then I am not interested in reading it. I know, very lame, but I do. In a mystery most of the time I wait, but sometimes I peak. I cheat. Its just my personality, I like to know if it will be worth reading. So it is kind of cool to me to be able to know what is the purpose of all this and that it will end the way that it should. Yeah I know, I am a weird woman. =)
