There is a readiness in the human heart that opens the way for healing. This readiness was present when Mrs. Eddy received the revelation of Christian Science. Shortly before her discovery in 1866 she had written a poem, "Our National Thanksgiving Hymn," each stanza of which ends with some form of these gracious words: "Thou knowest best!" Poems, p. 77; Here we glimpse the spiritual grace of her nature—so prayerful, so obedient—and the serenity of her thought.
Elsewhere Mrs. Eddy writes, "When the door opened, I was waiting and watching; and, lo, the bridegroom came!" Retrospection and Introspection, p. 23; This is not just an earthling wanting her own way. This is a servant of God seeking only her Father's will, that she might do it. So God has given the world through her the revelation of eternal Truth, to confirm that He alone knows what is best for all and that He will always show us the way.
There is no reason for us to struggle so hard to know what to do. When we can say with heartfelt joy, "Thou knowest best," we can behold our place in His eternal plan. God's appointment is infinitely wise, His arrangement tenderly paternal and maternal. He is our caring Father-Mother, who always reveals to us what is true spiritually; and thus we are able to recognize what is best humanly. We have only to ask in trust, listen in gratitude, and obey in joy.
