There is an old, short movie produced by the Church entitled, "The Bridge". In summary, it depicts the choice a father must make to sacrifice his son or the passengers of a train as he controls the switch that either will allow the train to cross the bridge and kill his son who is running across that bridge or swing the bridge in such a way that his son will survive while the train crashes. The following is a statement made by someone criticizing that movie and my response:
"It becomes trite, not majestic, when one tells a story like this. It makes the Atonement seem like a cheap parlor trick."
"Maybe for you and some other adults, but the basic construct can teach a powerful lesson for the children and teenagers for whom it was intended - who have no personal frame of reference for the concept of a parent who would watch a child die willingly and not intervene to provide help when He seems to have that power. The Atonement rarely gets addressed from the perspective of the Father who did not intervene. "God so loved the world that He gave His only begotten son." Most kids really don't get that, and many adults don't get it until they have kids. Some don't even get it then - and many of the common constructs of the Trinity essentially deny the need to understand how one separate Being (the Father) interacted with another (the Son). Without the foundational aspect of separate beings comprising one Godhead, the film makes no sense whatsoever.
Are there flaws in the analogy? Of course, there are flaws in all analogies. Can it make a very simple point in a powerful, visual way - something to help somewhat immature and inexperienced hearts and minds begin to grasp it? Yes. God, the Father, really did love all of us enough to allow His Son to die for us - enough to not intervene and save that Son while we all die. There really are two separate Beings in this narrative, and the Father literally was an active participant - first, of course, in strengthening Jesus in the Garden, but also in stepping back and "forsaking" Jesus as He died.
The film does a pretty good job capturing that aspect in a way that resonates in our current world, which is what analogies are all about - imperfect though they are."
