What we see now is like a dim image in a mirror. Then we shall see face to face.
Life perpetuates itself through diversity, and this includes the ability to sacrifice itself when necessary. Cells repeat the process of degeneration and regeneration until one day they die, obliterating an entire set of memory and information. Only genes remain. Why continually repeat this cycle? Simply to survive by avoiding the weaknesses of an unchanging system.
Your effort to remain what you are is what limits you.
And where does the newborn go from here? The net is vast and infinite.
