“In the process of coming unto the Savior and spiritual rebirth, baptism provides a necessary initial cleansing of our soul from sin. The baptismal covenant includes three fundamental commitments: (1) to be willing to take upon ourselves the name of Jesus Christ, (2) to always remember Him, and (3) to keep His commandments. The promised blessing for honoring this covenant is “that [we] may always have his Spirit to be with [us].” Thus, baptism is the essential preparation to receive the authorized opportunity for the constant companionship of the third member of the Godhead.”
