I was just thinking about an overused, and rather ridiculous, sermon illustration. It goes something like this:
A father works as an operator for a drawbridge which closes to allow a train to come across. One day, as a train approaches, just as he needs to close the bridge, he notices his young son playing among the gears of the bridge. If he closes the bridge, he will surely crush his son. If he takes time to save his son, the bridge will not be closed in time, and the train will derail, killing many passengers. As the story normally goes, the man chooses the train full of people over his own son.
I might have told that story as a young preacher, before the days of my own children. But my reaction to it now is simple: Not my son. If a train full of people depended on the life of my son, that train full of people would be out of luck. In fact, if the entire world depended on the life of my son to survive, the whole world would be screwed. Not my son.
That is what makes His love so amazing.
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.” (John 3:16)
