It's comforting. It restores man's faith in the orderliness of the Universe.
But let me put a bug into your garden of Eden. It is something I had forgotten, but of which I was reminded on another thread yesterday. (Also about Lincoln.)
If Lincoln was doing "God's Work", then why was his own personal life so tragic? One would think that a man doing what God wanted done, would be given some peace in his life.
It has always bothered me that Lincoln's son died, and that his wife went insane, because I couldn't square the one thing with the other. It made no sense that a man doing this great work for freedom and justice would be so badly treated.
Needless to say, it makes more sense to me now then it did when I was young. Maybe it will bother you the way it bothered me, and thereby lead you to looking at things in a different way.
Lincoln was not a particularly religious man, but his life was no more tragic than many Americans of his day, or indeed of other presidents.
Consider, for examples, the 1861 outgoing Democrat President Buchanan had no wife & children.
Preceding Buchanan, Democrat President Pierce:
So Lincoln's family life was not unusual for his time, and besides, God is known to have often selected flawed vessels to carry His message.
So nobody said that either Lincoln then or our current President now are saints, just that they are best suited to do the job which desperately needs done.
