WHY SHOULD WE BE AGENTS FOR GOD - WHAT HAS LIT THE FIRE UNDER US?

This set of quotes rocks it.

My siblings are very passive and I am sure they wonder why I am so outspoken and cannot shut my mouth.  I sound like a broken record at times - no, all of the time.....

This pretty much sums up the line of reasoning I have:

"No person whose soul is illuminated by the burning Spirit of God can in this world of sin and dense darkness remain passive. He is driven by an irresistible urge to fit himself to be an active agent of God in furthering righteousness and in freeing the lives and minds of men from the bondage of sin.”
-Marion G. Romney, In Conference Report, 4 Oct. 1941, p. 89.

“If I had been set to turn the world over, to dig down a mountain, to go to the ends of the earth, or traverse the deserts of Arabia, it would have been easier than to have undertaken to rest, while the Priesthood was upon me. I have received the holy anointing, and I can never rest till the last enemy is conquered, death destroyed, and truth reigns triumphant.”
-Parley P. Pratt, Journal of Discourses, 1:15

 I would love to know exactly what PPP meant by "the holy anointing".
