Man has lost sight of who he is as a human and that is why he is completely lost with no sense of direction in who he is, or his intended purpose. No person can be told the truth.
They have to see it for themselves in order to know through their own experience.That is how life works and that is the only way you can grow into who you really are.
A person can only discover life once they have come to a point of return to the light of the spirit.
