What the Bible says about God 'has gone off somewhere'
(From Forerunner Commentary)
A major point of instruction in this brief psalm is that, though it may seem to men as if God has gone off somewhere and is not paying attention, He is indeed very aware and patiently timing His interventions. Many evil people believe that God exists and created all things, but their belief is shallow. He is not part of their choices of conduct, so they live assuming that He is not personally managing His creation. Life goes on, they believe, without His involvement. This psalm refutes that, as do many other passages. It is a foolish, careless, and presumptuous basis for life's choices.
