My son Orson, hearken and hear and behold what I, the Lord God, shall say unto you, even Jesus Christ your Redeemer;
And more blessed are you because you are called of me to preach my gospel—
That's really good news for Orson Pratt, I suppose, but who was it that decided to call Orson to preach the gospel? God is pretty much saying "blessed are you for something I decided to do on my own." Which, in turn, can be roughly simplified even further to "I'm blessing you because I'm blessing you."
I hope his justifications for dumping on the people who have drawn his divine disfavor are a little more complex than that.
For behold, verily, verily, I say unto you, the time is soon at hand that I shall come in a cloud with power and great glory.
And verily, verily, I say unto you, I come quickly. I am your Lord and your Redeemer. Even so. Amen.
In just the last section, I pointed out that the Lord has been coming quickly for 190 years now—and it wasn't the first time that had come up. We could take into account God's skewed perception of time again, but even as this revelation applies to the specific person who God was addressing, the time was not soon at hand—Orson Pratt died in 1881. Why stress the urgency to him if he had another five decades of life ahead of him and he would still miss the Second Coming by more than a century?
