Love is the revelation of Life and Life is a manifestation of Love. The Universe is God's body, a necessary tool which some speak of as an illusion but a necessary one.
We grow through this field of struggle, until we get to the point where we see it for what it is and are free. Then our only purpose would be to teach this to others, or work for the manifestation of It's Will. This is what great Spiritual Masters, Christ, Buddha and others do.
