I have to agree that the whole thing sounds silly when we use the Jehovah's Witness exegetical approach.
And before I say this, I want to make it clear I am not encouraging anyone to adopt religion, reject religion, or anything else by the following...
The non-JW view is very different when you consider that most Christians believe Jesus was the incarnation of YHWH. While it was a popular pagan and heathen concept that gods in their incarnate form would rule as kings, the idea that the incarnation of the Jewish God and King would end up experience excommunication, torture, and death as a criminal by the hand of Jewish enemies (they regularly called Gentiles "sinners") is an outstanding invention, if nothing else.
When the theology that Jesus was YHWH in human form is used as a key, the story takes on a different meaning. In it the God of all the universe deigns to be born into poverty, to a woman who conceives this incarnation in morally questionable circumstances.
The birth goes unnoticed except by those marginalized in Jewish society, such as shepherds, and by heathen astrologers. When the Jewish ruler of the time learns of the child, this incarnate God is hunted as a target for slaughter.
Eventually the incarnate God of the Jews gets rejected by his own people, his own leaders of those who worshipped him. He gets excommunicated as a blasphemer and handed over to "Gentiles sinners" to die in nudity, hung on a new type of torture device invented by the Romans, the cross, on the date of the most important anniversary of Judaism, the Passover.
When the story is read from this vantage point rejected by the Jehovah's Witnesses, it is the story of a God that chooses to live among and identify with even the most insignificant among humanity. He purposely chooses a course that would lead to his experiencing suffering that even the worst criminals of the time experienced. God choose to experience what it is like to be poor, to be disbelieved, hated, rejected, as well as loved, to be part of a group, to have friends, to experience hunger, good food, joy, and the fear of death, as well as death itself.
God becomes human in order to raise humanity. He undergoes rejection to stop rejection. He experiences mortality in order to end mortality. God shares the life of man that man may share in the life of God. It is no longer a story about a sacrifice to appease a God who demands a death to cover Adam's sin, as the Witnesses teach. It becomes a story of a God sacrificing his life in order to give it to all his children.
Again this is not a plea to turn people into Trinitarians or get atheists to accept Christian mythology, no. But I do want to show up how poor a story the Witness theology makes of the Christian tale. According to the JW reading, the story is about a blood thirsty Jehovah who demands life for life, blood for blood. The other story is about a God who gives over his life, chooses to suffer, in order that life can be given to people, to end suffering, to stop the demand for sacrifice.
At least one story seems remarkable. The other, the Watchtower version, is a poor cousin, no different from the bloodthirsty demands of the heathen deities.
