[In] "the dispensation of the fullness of times, when God will gather together all things that are in heaven, and all things that are upon the earth, even in one," . . . the Saints of God will be gathered in one from every nation, and kindred, and people, and tongue, . . . and all things whether in heaven or on earth will be in one, even in Christ. The heavenly Priesthood will unite with the earthly, to bring about those great purposes; and whilst we are thus united in the one common cause, to roll forth the kingdom of God, the heavenly Priesthood are not idle spectators, the Spirit of God will be showered down from above, and it will dwell in our midst. The blessings of the Most High will rest upon our tabernacles.

Believing the time has now come, when it is necessary to erect a house of prayer, a house of order, a house for the worship of our God, where the ordinances can be attended to agreeably to His divine will. . . . it behooves the Saints to weigh the importance of these things, in their minds, [and] . . . resolve to do all they can, and feel themselves as much interested as though the whole labor depended on themselves alone. By so doing they will emulate the glorious deeds of the fathers, and secure the blessings of heaven upon themselves and their posterity to the latest generation. To those who feel thus interested, and can assist in this great work, we say, let them . . . assist in the rolling on of the Kingdom, . . . and rise higher and higher in the scale of intelligence until they can "comprehend with all Saints what is the breadth and length, and depth and height; and to know the love of Christ which passeth knowledge."
History of the Church, 4:186.
