"Hear now, O house of Israel; Is not my way equal?" (Ezek. 18:25) is a Scriptural basis for the statement in "Science and Health with Key to the Scriptures" by Mary Baker Eddy (p. 110), "The equipollence of God brought to light another glorious proposition,—man's perfectibility and the establishment of the kingdom of heaven on earth." The connection between these three—God's equipollence, "man's perfectibility and the establishment of the kingdom of heaven on earth"—may not at first be readily discerned by a cursory reading.
"Equipollence" means equality of power, and applied to the Supreme Being it means that God's power is equal in every way, everywhere, every hour. This must have been what the Psalmist had in thought when he declared (139:8-10): "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."
The perfection of God is axiomatic; it follows that perfection is equipollent, and since God is the only cause, perfection must characterize every effect of this one and only cause. Hence man's perfectibility is brought to light by the equipollence of God, as Mrs. Eddy has revealed. This unveils the unreality of all the various claims of inequality, personal, national, international, and the various phases of physics —time, space, and substance.
