From D. Todd Christofferson, 4 Apr 2015
'Knowing why we left the presence of our Heavenly Father and what it takes to return and be exalted with Him, it becomes very clear that nothing relative to our time on earth can be more important than physical birth and spiritual rebirth, the two prerequisites of eternal life. This is, to use the words of Dietrich Bonhoeffer, the “office” of marriage, the “post of responsibility towards … mankind,” that this divine institution “from above, from God” occupies. It is the “link in the chain of the generations” both here and hereafter—the order of heaven.'
