One of the most profound realizations I've had in recent years is that the Second Coming is something that we can effect through our "repentance" (metanoia = a change of mind, or conscious perception of the world).
Many religious people believe that the spirit or soul is the ego-self, our personality, the person we think we are in our heads, our psychological "self," with all our memories and experiences and relationships, etc. But none of this existed at our birth.
At this time of year the Christian world celebrates the birth of Jesus during a holy day we call Christmas. This birth happened some two thousand years ago, which brought into the world a man who many billions of people today have come to adore and worship as both human and divine.
We awaken in Christ’s body as Christ awakens our bodies, and my poor hand is Christ, He enters my foot, and is infinitely me.
When the false self dies—the ego, the old creature, the constructed personality, the illusory self, the separate independent idea of one's self, the man of sin, the son of perdition, the natural man, the carnal mind—when this is seen for what it really is, when it is revealed in truth, when it is put off, taken out of the way, when it is crucified and passes away, then the true Self is revealed in glory.
