How often we hear the remark made, sometimes half heartedly, then again with a certain pathetic yearning in the tone. "Oh, if I just had the understanding that some people have, or if I could talk as well as some people do, I would not mind giving a testimony at a Wednesday evening service, and how glad I would be to give this healing truth to those in need of it!" Let us stop a moment and analyze this desire, for if it be a true one it is prayer, according to the teaching of our dear Leader (see Science and Health, p. 1). Again, on page 326, she says: "Working and praying with true motives, your Father will open the way. "Who did hinder you, that ye should not obey the truth?" Who or what is this that claims so little intelligence and understanding, and no ability to give out the truth? Is this the Father's own child, to whom He has given all things, or is it mortal man, who does not know what it means to be either a receptacle or a channel for the truth? And could mortal man ever do anything in or of himself? Is not this the same kind of plea which mortal mind presented to Moses, seeking to hinder him from carrying God's message of deliverance to the Israelites? Moses said, "I am not eloquent, ... I am slow of speech, and of a slow tongue." Mortal mind can always find some excuse to hinder our progress and keep us from being about the Father's business. It is then we need to ask, What is man's birthright, and has not God given him dominion over all? Paul declared, "I can do all things through Christ which strengthened me."
God's reply to Moses was: "Who hath made man's mouth? ... Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say." Our first step then must be expressed by a readiness to obey, a letting go of self-will and self-consciousness, and when human thought is emptied of self one is ready to do the Father's will. God said, "Go, and I will ... teach thee." Faith is always required before we can enlist in the Father's service. There must always be a loving confidence in the divine All-power, since God never gives the supply in advance of the demand.
In Matthew's gospel we find a promise given the apostles, when they were sent on their healing mission, similar to that given Moses: "When they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. For it is not ye that speak, but the Spirit of your Father which speaketh in you." Moses was not ready to heed the divine command at the time he was called; perhaps he had not learned that divine Mind is the only intelligence. Relying as he seemingly did on human ability and wisdom, he had not the faith or courage to go forward without seeing how the work was to be accomplished, and so God chose Aaron to deliver the message.
