As a Christian, one might think that I would be held by the power of the cross.
But no symbol holds power over me. And no Christian should be held by any symbol, just as (by the Ten Commandments) they should not worship any graven image of God, gods or any other force in the universe.
Physical symbols are of this physical realm. They are based upon the continuity of this action-reaction reality. Returning to God requires that we understand our own non-physical and discontinuity-bound nature. Creation is a discontinuous act. So are forgiveness and inspiration. They break with the continuity of reality and the chains of the past that would otherwise have prevented them.
God wants us to be fearless and confident, but He also wants us to be humble (without ego), which is also discontinuous in nature, because the humble person does not depend upon titles, degrees, possessions, money, allegiances, power and the like.
I like the symbol you used. It is a two-dimensional representation of a three-dimensional pattern of universal energy. You can learn more about it in the video, "Thrive."
