It is one thing to look back upon the events of history. It is another to regard our own time. We have the Lord’s assurance that he will bless and prosper his people if they will keep his commandments and remember to look to him as the source of their blessings.
On the other hand, we must not forget that these blessings are conditional. As King Limhi warned his people:
“For behold, the Lord hath said: I will not succor my people in the day of their transgression; but I will hedge up their ways that they prosper not; and their doings shall be as a stumbling block before them”
