[sup]4[/sup] For he chose us in him before the creation of the world to be holy and blameless in his sight. In love [sup]5[/sup] he predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will-- [sup]6[/sup] to the praise of his glorious grace, which he has freely given us in the One he loves.
Eph 1:4-6 (NIV)
We were created for Gods pleasure and will. First this may sound ghastly. For his pleasure and will? How completely selfish... But look into what his pleasure and will is before condemning him. God is love, that is why we were created. If God is love, he cant exist without someone to love, thus man was created. You ask, well why were we created on earth? Well, to coexist in with God in a beautiful place Gen. 3:8. But after the fall, God could no longer live among us because he cannot be in the presence of sin. Yet it remained, that Gods pleasure and even his very nature, is to love us, more than we can possibly fathom.
Yeah, ok... thats why we were created, but still, we have to have a purpose since were here other than just soaking up Gods love. We do have purpose, God has plans for each and every one of us. These plans can only be realized after we are in a relationship with him, though. Until we accept him as our god, our lives have no purpose. Since we were created in his image though, which is only complete once we have been transformed by accepting Christ as our Lord and savior, our existence is based around love. Our sole purpose as Christians is to love God and love people. Simple in words, impossibly complex in actions. The depth to which we are required to love is not humanly conceivable, let alone actually being able to act it out. To love God we must get to know him, this is only possibly through talking to him and reading his word. Once we begin to understand God and his love for us, we will begin to understand how we are to love others. Then asking God to use us to pour out his love through us.
But we are also created for his will. This does not sound like a very appealing thing. Every person has their own aspirations and desires. Keep this in mind though, God will always do what is best for his kingdom, and what is best for his kingdom is best for us, since we are a very big part of his kingdom. See Romans 8:18.
So, love God, love others and your life will be blessed and filled with understanding.
