The psalmist has been filled with pressures of anxiety and depression, and unable to remain quiet any longer. He has seen himself as worthless, living in a hopeless world, amounting to nothing more than a shadow in his existence.
And now, he complains, what do I wait for?
He is beginning his turning to God realizing that waiting on the world, there is nothing in the world to bring about security or contentment or anything else for that matter. And so the question, implied, where does one find cheerful or comforting views in life?
When contemplating the world in ones pursuits, the course of things in life are nothing more than a shadow, and a mysterious and empty pursuit of the things in life, that are temporary, and seemingly have no permanent purpose.
And so the psalmist realizes that hope is not in the world, but hope lies within God. And, one’s access to God is by means of the written word. And in attaining access one has to learn the written word, namely by means of receiving instruction in a daily Bible study.
And only then, when a person wakes up, and knuckles down, and dedicates himself to the pursuit of learning about God and truth, through a daily study, will the eyes be opened, and the real hope, recognized.
