George Q. Cannon said,

If you read of the great men of antiquity, or of modern times, you will find that in almost every instance they have had great mothers, who have moulded and fashioned the plastic minds of their sons according to their own notions of greatness, and sent them forth to battle with the circumstances of life, like gods almost. Great interests are in the hands of mothers. God has reposed in them great power; if they wield that power of good it will be productive of peace and happiness and exaltation to them. They will be blessed in seeing the greatness of their posterity. Their hearts will be gratified in having a posterity who will rise up and called them blessed.

(George Q. Cannon, Journal of Discourses 11:338-339)
