“As we shall see hereafter, those who were wholly consecrated to God and had reached high attainments in their unity with the Father, were called “Yahveh” by Moses. Jesus the Christ, said, “I and my Father are one.” We know that our Christian brethren thinking upon this without further light have concluded that Christ was one of the triune Godhead. That is true, because God has a threefold manifestation. First, as the Father or Producer of all that is – the Creator. Second, as the Holy Spirit, translated the Holy Ghost, the active agency. Third, as manifested in human form, the son of God.
We read of Christ that he was manifest, that he might bring many sons unto God. Again, he said, in regard to that oneness in his notable prayer: “Neither pray I for these alone, but for them also which shall believe on me through their word; that they all may be one; as thou Father art in me, and I in thee, that they also may be one in us.” Here Jesus makes it plain that there are not many Gods, but one, but that there are many manifestations of God in the form of his sons.
But as soon as a man becomes truly a son of God, his will becomes one with the Father’s will, thus they are no more two, but one. For all there is of life, of existence, of being, is the mind, for God produced all things by a word, viz., a thought formed in the mind, a decision reached and sent out by the force of the will, endowing the thought-form with potentiality capable of working out and bringing into manifestation the thing decided upon.
Jesus was the last messenger who stood before the world as the ultimate embodiment of that creative word, a finished man, a son of God, a man in whom God was incarnated and through whom he found complete expression, as Christ said, “I can do nothing of myself, the Father that dwelleth in me, He doeth the works.”
Thus, the name of God is the name of the divine attribute or active agency that produced all manifestation and lies beyond, beneath, and overrules all action. Here words fail to express fully the deep, comprehensive meaning of that great name, but he that would be wise and strong and godlike, should muse much upon the signification of this wondrous name of the God of the universe, Yahveh – the “I will be, what I will to be.””
