Now I am going to say something that maybe I could not prove, but I believe is true, that we have a great many members of this Church who have never received a manifestation through the Holy Ghost. Why? Because they have not made their lives conform to the truth. And the Holy Ghost will not dwell in unclean tabernacles or disobedient tabernacles.
The Holy Ghost will not dwell with that person who is unwilling to obey and keep the commandments of God or who violates those commandments willfully. In such a soul the spirit of the Holy Ghost cannot enter. That great gift comes to us only through humility and faith and obedience. Therefore, a great many members of the Church do not have that guidance.
Then some cunning, crafty individual will come along teaching that which is not true, and without guidance which is promised to us through our faithfulness, people are unable to discern and are led astray. It depends on our faithfulness and our obedience to the commandments of the Lord if we have the teachings, the enlightening instruction, that comes from the Holy Ghost.
When we are disobedient, when our minds are set upon the things of this world rather than on the things of the kingdom of God, we cannot have the manifestations of the Holy Ghost. Did you ever stop to think what a great privilege it is for us to have the companionship of one of the members of the Godhead? Have you thought of it that way? That is our privilege, if we keep the commandments the Lord has given us.
