One of the most freeing spiritual facts we can come to understand through Christian Science is that God is the only I or Ego, that God is divine Love, the essence of all that is real.
A linchpin of the system of Christian Science is that man is the outcome of God, always spiritual and in unity with Him, and never a mortal wanting to be united with Him.
The spiritual origin and being of man is so far beyond the comprehension of the physical senses that it is safe to say nobody has more than a slight acquaintance with the true nature of even his nearest human relatives and friends.
It's not unusual for thinking individuals to wonder just what they really are and what they are here for—to speculate on their origin, their purpose, their goal.
