What does Henry allude to in the ants on the burning log?

Henry uses the allusion of the Messiah.

I remember thinking at the time that it was the end of the world and a splendid chance to be a messiah and lift the log off the fire and throw it out where the ants could get off onto the ground. But I did not do anything but throw a tin cup of water on the log, so that I would have the cup empty to put whiskey in before I added water to it. I think the cup of water on the burning log only steamed the ants.
