"A Deep sincerity is sure of success, for God takes care of it," writes Mary Baker Eddy in "The First Church of Christ, Scientist, and Miscellany" (p. 203). Mrs. Eddy was a deeply sincere seeker of God. Otherwise the great truths of divine Science could not have been revealed to her. Surely it was her humility, deep sincerity, and love for God and man which enabled her to present these truths to mankind through Christian Science.
Among the Old Testament characters is Joshua, that honest soldier of God, who, when trying to rouse the Israelites from the bondage of material worship, demanded of them (24:14), "Now therefore fear the Lord, and serve him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood, and in Egypt; and serve ye the Lord." Abraham, Moses, Elijah, and Elisha also must have sought God in sincerity and in truth, for they gave convincing proof that this single-minded seeking was not without its reward.
Jesus, we know, ever sought and obeyed his Father's will, and he revealed this will to others. After the ascension, when the disciples better understood the Master's teachings, they too continued in his work; though, of them all, John must have gained the clearest conception of God, for to him only was the vision of the Holy City revealed.
