Writing in the Christian Science Sentinel of May 30, 1903, Mrs. Eddy said (The First Church of Christ, Scientist, and Miscellany, p. 12): "This was an emphatic rule of St. Paul: 'Behold, now is the accepted time.' A lost opportunity is the greatest of losses. Whittier mourned it as what 'might have been.' We own no past, no future, we possess only now." In the next paragraph, speaking of children and their good deeds, she commented: "The good they desire to do, they insist upon doing now. They speculate neither on the past, present, nor future, but, taking no thought for the morrow, act in God's time."
The omnipresence of God, good, is proof that good in its infinite variety of expression is everywhere and therefore is present for everyone at all times and is thus available now. "Do not I fill heaven and earth? saith the Lord" (Jer. 23:24). Good in infinite diversification is everywhere divinely natural and normal to man now.
Whatever is true has always been true, will ever be true, and it is true now for everyone. Likewise, whatever is untrue has never been true, will ever be untrue, and is unreal and untrue now. Error can never be true, because it is a mistake regardless of how long or how awful it may have seemed to be. Healing in Christian Science consists in the refusal to accept the false presentments of evil or in the elimination of evils that have been permitted to enter thought and being. Thus, to heal instantaneously, one repudiates each aggressive mental suggestion the instant it presents itself, or, having accepted it as a belief, discards it the moment its illusive nature is seen. Healing takes place the very instant that one sees the wholly illusive nature of any material falsity and replaces it with divine ideas of perfection.
