When the Holy Ghost leaves, it simply leaves without fanfare or flurry. There is no pronouncement. No drama. The still small voice just goes silent.
However, for those with ears to hear and the humility to receive, The Holy Ghost rushes in.
God pouring down knowledge upon the heads of the saints has been compared to the mighty rushing waters of the Missouri. But, times have changed since then. Man can attempt to dam the waters for a time, but the relentless waters will find a way to break through somewhere else. And, when men attempt to dam up the living waters, they only damn themselves.
In 1860, a group of saints who dared to refuse to follow the leadership of Brigham Young, reorganized themselves, sustained a prophet, and in the intervening time has received nearly a hundred oracles in their D&C, including instructions regarding the proper duty of evangelists, women being called to positions which require priesthood authority, and gay men and women being accepted as equals within the body of Christ.
In 1985, a group of gay men and women in Los Angeles dared risk excommunication from the church and ostracism from the the gay Mormon group Affirmation, and dared to ask God for further light and knowledge concerning teaching the Gospel to Gays and Lesbians. What followed was a complete dispensation of Priesthood and dozens of revelations concerning how the Gospel functions in a same-sex environment.
Revelation isn’t dead. Not as long as there is at least one Priesthood holder left on earth.
