You must have faith to pray. You must have faith to ponder the word of God. You must have faith to do those things and go to those places which invite the Spirit of Christ and the Holy Ghost.

Humble prayer to our Heavenly Father, in deep faith in Jesus Christ, is essential to qualify us for the companionship of the Holy Ghost.

With the help of the Holy Ghost, we can watch over ourselves. We can pray to recognize and reject the first thoughts of sin. We can pray to recognize a warning not to speak words which would hurt or tempt someone else. And we can, when we must, pray for the humility and the faith to repent.

With faith and obedience practiced long enough, the Holy Ghost becomes a constant companion, our natures change, and endurance becomes certain.

The Holy Ghost is a comforter and a guide. But it is also a cleansing agent. That is why service in the kingdom is so crucial to enduring. When we are called to serve, we can pray for the Holy Ghost to be our companion with assurance it will come.

The Holy Ghost is a personage of Spirit: a separate and distinct member of the Godhead.
