The Beatific Vision may be thought of as a state of being in which all creation participates as a manifestation of His glory. We being persons, it involves communion with God, who brings us into being within the ocean of His infinite compassion. In order for this complete and loving connection to be possible, its possession necessarily requires a contribution on our part to that relationship. The Beatific Vision is offered and ultimately bestowed upon us as a consequence of our acceptance of His Divine will.
Every creature has a will of its own, in keeping with its nature. Those beings who are below us, from the material dust of the universe to plants and animals, are a part of the eternal wonder of creation, but determined and unable to give of themselves. We and the angels above us are different in that we have a free will, which is a manifestation of our capacity to know love and act. We make of ourselves what we will in the moral universe.
The Centre of existence being Love itself, in order to know Him, all that have the capacity to do so must themselves be transformed into love. We must give ourselves totally to Him, as did the angels who followed Him. Those that did not, those messengers who chose to convey their “truth” rather than the Truth, fell as did we in following their false promises.
In a way it’s a test, but it seems more rational to think of it as the destiny for which we are meant and the reason for our existence. As did the angels before us, they at the instant of their creation and we over time, we become who we are through the exercise of our free will. Within eternity, we choose to be either with God or against Him. To be with God is to be in loving union with Him at the very Core of all His glory; against Him, we have only ourselves.
