Números 4:15

Verse 15. And when celestial love and its truths thus protect the true worship of the Lord, and all things which minister thereto, in order that there may be progress in spiritual life, then it is the function of the spiritual heaven and the spiritual man, who is a heaven or is preparing for heaven, to promote such progress, but he cannot perform the functions proper to the celestial loves, nor can he realize the celestial things thereof, for this would cause the destruction of his own life of charity; but nevertheless spiritual love ministers to celestial love in the worship of the Lord and the work of salvation.
