In the Lord’s church we are told to pray without ceasing. How? By living with the constant companionship of the Gift of the Holy Ghost. To be in continual communion with the Father through His Son Jesus Christ, by the Gift and power of the Holy Ghost.
For as the Holy Ghost is a revelator, and revelation is communication, our communication with the Father is as we commune with Him our thoughts, feelings and prayers. He then whispers back to us through the still (comforting), small (piercing) and perfect voice of the Holy Spirit.
With this communion, we learn great things, receive guidance, and His will and promptings help us avoid deception and all other pitfalls.
To obey this law to pray without ceasing, in the which we have the constant companionship and influence of the Gift of the Holy Ghost, which is different than just the influence of the Holt Ghost, we need to first have sacred priesthood ordinances performed on our behalf, through covenant, in The Church of Jesus Christ of Latter-Day Saints.
To be partakers of this then, we must live our lives completely to the very best of our knowledge and ability, to keep our covenants, commandments and promises. In this we can then truly always have His Spirit to be with us, thus fulfilling the commandment to truly pray without ceasing.
