Giving credence to the theory that God, good, is not ever present is the underlying source of the illusion that sin, disease, and death are real. The recognition of the omnipotence, omniscience, and omnipresence of immortal Being eliminates this false sense of error and brings joy, peace, health, and harmony into our experience.
As Christian Scientists we accept the fact that God is All and the only creator, but do we actually comprehend the far-reaching implications of this truth? The Psalmist glimpsed its magnitude when he declared (Ps. 139:7-10): "Whither shall I go from thy spirit? or whither shall I flee from thy presence? If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there. If I take the wings of the morning, and dwell in the uttermost parts of the sea; even there shall thy hand lead me, and thy right hand shall hold me."
In "Science and Health with Key to the Scriptures" Mary Baker Eddy says (pp. 203, 204), "God is at once the centre and circumference of being." Since God, good, is everywhere, there can be no absence of good —no evil, regardless of what error's manifestation may appear to be.
