His talk addresses the difference between priesthood power and priesthood authority.
My mind raced around to all different thoughts from leadership in the home to people complaining that woman in the church are dominated by men because of the priesthood. (Personally, I don't see a need for he to have the priesthood authority. I have the ability to access the power of the priesthood anytime I want.)
Elder Ballard taught that it is the power of the priesthood that the "heavens and the earth were created," that miracle happen with, that helped the Savior "to endure the unbearable pain of Gethsemane." It is the power that has been given to "bind in heaven that which is bound on earth." It is "a sacred and essential gift of God."
Most importantly the power of the priesthood "comes only when those who exercise it are worthy and acting in accordance to god's will."
See. I cab access all of that.
Elder Ballard pointed our that just as it really does take two to create children, it take a husband and wife to exercise true power in the priesthood through righteous living. It takes obedience, love, humility, and patience. It takes service as we help the weak and strengthen others... particularly in our families.
Sadly, I have seen many priesthood holders, and those that love them, wither and nearly become destroyed because of neglect. Elder Ballard's story of the tomato plant reminded my of that. I have also seen some come back to life because of the loving patience of other continually inviting them to bask in the Light and to drink from Living Water. I have also experienced this feeling for myself.
I remember listening to this talk and thinking of the little struggling tomato plants in my life. I remember resolving to do better at providing the light and offering the water.
Elder Ballard suggested walking the Church training video. You can watch those training videos her: http://www.lds.org/training/wwlt/2013/the-power-of-god?lang=eng
At any rate, great talk.
