In verse 11, Lehi spoke to his family about the Jews’ dwindling in unbelief. Similarly, marriages don’t always just fail. The strength in them dwindles away a little at a time. By the same token, the strength in marriage isn’t at full strength in the beginning, either. It develops a little at a time. A marriage is a living thing that requires nourishment. The best way to nourish a marriage was “prepared for all…from the foundation of the world” (verse 18). It is to rely on the gospel of the Redeemer (see verse 6).
