The forty-second Psalm expresses in beauty and poetry, as do many of our lovely Psalms, the feelings of the Psalmist as he alternates between longing and disappointment, despair and hope in God. But he finally reaches a state of peace and harmony which is summed up in the last verse as follows: "Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God: for I shall yet praise him, who is the health of my countenance, and my God."
It would seem that most people, including children, have at some time or other suffered from a sense of disappointment when their dearest wishes and hopes have not been fulfilled. And if it should happen that those they love and trust disappoint them, the experience can be a sad and sharp one.
Mortals have a way of expecting and looking for good where no satisfaction lies. Gazing in the wrong direction, that is, towards the material sense of life, their hopes must deceive eventually; they cannot be fulfilled in joy, because they are not based on reality or Truth.
