God's purpose for our lives is that we become like Jesus.  We could never do that on our own, so God is working everything in the universe to bring about that good result--His Good Purpose!  In fact, we can't even help.  We can only receive it.  What we are receiving is a restoration of our relationship with God through the blood of Christ on the cross--which is God's gift to us.  As we abide in the presence of God, we are changed from glory to glory.
