In totaling a column of figures, we wouldn't say that the sum obtained is partly correct. We know it is either correct or incorrect. Mathematical rules simply do not allow for occasional incorrectness, or for an answer that is partly correct.
Can't we find it equally obvious that God, who is omniscient Mind, flawless divine Principle, could not and does not allow for any divergence from His standard of perfection? Does our concept of God give Him less precision and dependability than the law of mathematics? Is God ever forced to compromise His standard?
For many, the fact of God's allness and perfection seems too abstract to have any practical meaning in solving humanity's problems. The human mind is so conditioned to think in finite, material terms that it has difficulty taking in such a concept. One of the conclusions that human thought finds especially difficult to accept is that all must be good if God is good and All. Mankind usually does not expect anything to be wholly good—wholly flawless and perfect. Many are satisfied if the good merely outweighs the bad.
