"The most renowned of all the Prophet’s sermons was given at general conference in April 1844 as a funeral address in honor of his friend King Follett who had died in a construction accident. Joseph Smith spoke for over two hours mentioning at least thirty-four doctrinal subjects, including the importance of knowing the true God, the way to become as God is, the plurality of gods, eternal progression, the importance of the Holy Ghost, the nature of intelligence, the unpardonable sin, and little children and the Resurrection.
One of his most profound messages concerned God and man’s destiny in relationship to him. He declared, “God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! . . .
“. . . you have got to learn how to be gods yourselves . . . by going from one small degree to another, and from a small capacity to a great one; from grace to grace, from exaltation to exaltation, until you attain to the resurrection of the dead, and are able to dwell in everlasting burnings.” Man, then, is to become like God now is. Joseph also explained the “first principles of consolation” for those mourning for the righteous dead: “although the earthly tabernacle is laid down and dissolved, they shall rise again to dwell in everlasting burnings in immortal glory, not to sorrow, suffer, or die any more, but they shall be heirs of God and joint heirs with Jesus Christ.""
