The [first] vision of Joseph Smith made it clear that the Father and the Son are separate personages, having bodies as tangible as the body of man. It was further revealed to him that the Holy Ghost is a personage of Spirit, distinct and separate from the personalities of the Father and the Son [seeD&C 130:22].
. . . . . man is the most important of all our Father’s creations. In the same vision given to Moses, the Father said: “And as one earth shall pass away, and the heavens thereof, even so shall another come; and there is no end to my works, neither to my words. For behold, this is my work and my glory—to bring to pass the immortality and eternal life of man.” [Moses 1:38–39.]
From this, and other scripture, I say, we learn that the great work of the Father is to bring to pass the salvation of his children giving unto each that reward which each merits according to his works. I feel most assuredly that our Father in heaven is far more interested in a soul—one of his children—than it is possible for an earthly father to be in one of his children. His love for us is greater than can be the love of an earthly parent for his offspring.
His voice has been one inviting all men to come to his Beloved Son, to learn of him, to partake of his goodness, to take his yoke upon them, and to work out their salvation by obedience to the laws of his gospel. His voice has been one of glory and honor, of peace in this life, and of eternal life in the world to come.
