The purpose of gospel habits is primarily to receive the Holy Ghost

 "everything the Savior’s gospel teaches us to do and become is intended to bless us with the companionship of the Holy Ghost.

"Consider the reasons we pray and study the scriptures. Yes, we yearn to communicate in prayer with Heavenly Father in the name of His Son. And yes, we desire to obtain the light and knowledge available in the standard works. But please remember that these holy habits primarily are ways whereby we always remember Heavenly Father and His Beloved Son and are prerequisites to the ongoing companionship of the Holy Ghost.

"Reflect on the reasons we worship in the house of the Lord and in our Sabbath meetings. Yes, we serve our kindred dead in the temple—and our families and friends in the wards and branches in which we live. And yes, we enjoy the righteous sociality we find among our brothers and sisters. But we primarily gather together in unity to seek the blessings of and instruction from the Holy Ghost.

"Praying, studying, gathering, worshipping, serving, and obeying are not isolated and independent items on a lengthy gospel checklist of things to do. Rather, each of these righteous practices is an important element in an overarching spiritual quest to fulfill the mandate to receive the Holy Ghost. The commandments from God we obey and the inspired counsel from Church leaders we follow principally focus upon obtaining the companionship of the Spirit. Fundamentally, all gospel teachings and activities are centered on coming unto Christ by receiving the Holy Ghost in our lives."
