In addressing why we’re here we would need to go back to the beginning, but this would take a long time considering the Universe and The Infinite Presence that created it, is eternal. There is infinitely more than what we could possibly imagine, regarding why we are here right now, on this planet. (see article, “The Theory of Everything,” by Myswizard, and Karma articles for some of the explanations)
More than a few very influential spiritual writers have said that we are here to remember that we are spirit. Other writers of a clerical nature have used references to the Bible regarding our purpose here on earth. The problem with using Scripture from the Bible and other High calibrating written works, isn’t merely because these words were written thousands of years ago, but due to the fact that in our modern society, ancient explanations for that which is humanly unexplainable, is difficult at best. There is also the problem of thoughts and ideas being lost in translation throughout time. Simple explanations are generally the wisest, and the best path to follow when seeking to become enlightened, which is our Highest purpose.
What it is that we are here for or to remember is in question. If there is remembering to do, it is to recall what it is we came here for and what we are. The statement that we are already enlightened and we just have to remember that, is also false. We cannot be that which we never were in the first place.
The spirit has definitive levels of consciousness as we do in the material world. As we graduate the levels of consciousness, we become that which we have evolved to, as opposed to remembering something that we never were. Although rare, to become enlightened is a goal of spirit. It is a natural part of the evolution/creation of the totality of all that exists. Since we are in a constant state of evolvement, we cannot possibly all be enlightened until we’ve all become one with the Godhead. There will always be levels of existence. To think otherwise is spiritual capriciousness.
No one person is able to tell you what it is you should be, supposed to be, or have to be doing.* This may leave tens of thousands of books on the shelf. An earthly experience is a personal journey of the Self. The way in which we can look at our human life is with reverence, as a gift from Divine Source. Religious wisdom is complementary to that over and above what we are, as long as it remains within the grace of God’s wisdom and without the influence of human, ego-oriented constricts (which is relative to rules, laws, and regulatory features of religion). What we choose to do with this life is entirely our own free will, which is also a God-given gift. We can be anything we choose to be as a spirit living temporarily with a human body. It is only one’s level of consciousness that will dictate how that life is lived. From that point on, what it is we do is not as important as what it is we are, as we do it.
