The Right to Have the Heavens Opened and Receive Revelation
Doctrine and Covenants 107:18–19
18 The power and authority of the higher, or Melchizedek Priesthood, is to hold the keys of all the spiritual blessings of the church—
19 To have the privilege of receiving the mysteries of the kingdom of heaven, to have the heavens opened unto them, to commune with the general assembly and church of the Firstborn, and to enjoy the communion and presence of God the Father, and Jesus the mediator of the new covenant.
President Spencer W. Kimball said of the restoration of the Melchizedek Priesthood:
“[The restoration of the Melchizedek Priesthood] is an event of supreme importance to man in this dispensation, for the priesthood is the power and authority of God delegated to man on earth to act in all things pertaining to the salvation of men. It is the means whereby the Lord acts through men to save souls. Without this priesthood power, men are lost. Only through this power does man ‘hold the keys of all the spiritual blessings of the Church,’ enabling him to receive ‘the mysteries of the kingdom of heaven, to have the heavens opened’ unto him (D&C 107:18–19), enabling him to enter the new and everlasting covenant of marriage and to have his wife and children bound to him in an everlasting tie, enabling him to become a patriarch to his posterity forever, and enabling him to receive a fulness of the blessings of the Lord.”
