God didn’t just create the world, then walk away. He is still very present and engaged in every part of the universe. It is his clothing, his home, his transport, his workforce, his headquarters (vs 2–4).
He is completely in charge (v 5). No creatures are sheltered unless God covers them (vs 16–18). No humans or animals eat unless God provides for them (vs 14,15,21,27,28). No one breathes unless God breathes on them first (vs 29,30). He sets limits to the destructive power of water, and controls and determines its ability to give life (vs 6–13).
Ancient cultures often grasped these theological truths far better than we do today. But nowadays some city children don’t know, for example, that milk comes from a cow and, even as adults, our confidence in technology can insulate us from comprehending our dependence on our Maker.
But we cannot yet, I don’t think, make tectonic plates shudder or get a volcano to erupt (v 32) – nor can we avert such calamities. The rhythm of life throbs in time with the beat that God has set (vs 19,20,22,23). When we truly understand this, the natural response is to praise him and long to please him (vs 33,34).
