This time Nebuchadnezzar comes and he destroys the city of Jerusalem and he burns the temple to the ground and he takes the entire population captive. It was a judgment again sin. This means it was no chance happening. This is a picture of the sovereignty of God. He is in control, not only when good things happen, but when bad things happen, too.
Every person is to be in subjection to the governing authorities.
It is God who raises up presidents and potentates. He is the ultimate authority on planet earth. He is the only real superpower. And even when an evil nation like Babylon comes to power, we find that God is the One who has ordained that it should be. It means that absolutely nothing can ever come into your life without having passed through a nail-scarred hand.
