Sidney Rigdon was the first counselor in the first presidency. But the Lord still said to him:
D&C 93:44 Verily, I say unto my servant Sidney Rigdon, that in some things he hath not kept the commandments concerning his children; therefore, first set in order thy house.
Even with a calling as important as that, Sidney needed to “first set in order” his own house.
We tend to think of big callings as being more important than “little” normal things like husband, wife, father, mother. But the Lord sees things differently than we do. The Lord specifically told Sidney that he needed to put his house in order “first”. That was priority number one. How could he do his other calling without the critical spiritual foundation properly in place?
