Surrender has nothing to do with repentance, you are not evil or a sinner. You were never born separate from God, except within the ideas, theologies and beliefs of those who created the idea of God out of their own fear and ego.
God was created out of the fear of the ego to admit its limitations. God is the greatest ego of all and he has been worshiped for centuries to sustain and give meaning to the individual ego through the false identity.
Man created God out of fear to justify his actions in controlling others and dominating the physical earth. Guilt and Sin were introduced as a smokescreen to prevent the discovery of the truth through individual inner examination or meditation.
You were told to believe, not because a God exists to reward you for deeds done in the flesh, but because by believing you would become a prisoner to ideas, theologies and beliefs that prevent the discovery of the truth within you.
