There was this kid who came from a poor family. He had no good options in life so he signed up for the military. After a few years he was deployed to a conflict infested, god-forsaken desert outpost. It was the worst tour of duty he could have been assigned. It was going to be hot and dangerous. Everyday he had to live with a hostile populace who hated his presence and the very sight of his uniform. Plus, the place was swarming with insurgents and terrorists.
Anyhow, one morning the solider goes to work and finds that he's been assigned that day to a detail that is supposed to oversee the execution of three convicted insurgents. The solider shakes his head. He didn't sign up for this. His life just totally sucks. "They don't pay me enough," he thinks, "for the shit I have to do.
"He doesn't know he's going to be executing the Son of God that day. He's just going to work, punching the time clock, keeping his head down. He's just trying to stay alive, get through the day, and send some money back home to Rome.
And this is why, I think, Jesus prays, "Father forgive them, for they do not know what they are doing.
"Few of us do.
