The cry of the humbled.
The psalm belongs to the age of true national contrition, when nothing would satisfy but deliverance from sin, as well as from its punishment (comp. Lamentations 3:55; Jonah 2:2). When men are disheartened and depressed, overwhelmed with anxieties and troubles, we familiarly speak of them as "down in the depths." It is a natural and universal figure. "On the hills" represents excitement and joy; "in the depths" represents depression and anxiety. "This psalm is distinctly a song of ascent, in that it starts from the very lowest point of sell: abasement and consciousness of evil, and rises steadily, and, though it may be slowly, yet surely, up to the tranquil summit, led by a consciousness of the Divine presence and grace." "The psalmist thinks of himself as of a man at the bottom of a pit, sending up to the surface a faint call, which may easily be unheard. He does not merely mean to express his sense of human insignificance, nor even his sorrows, nor his despondency. There are deeper depths than these. They are the depths into which the spirit feels itself going down, sick and giddy, when there comes the thought, 'I am a sinful man, O Lord, in the presence of thy great purity.' Out of these depths does he cry to God."
I. THE DEPTHS ARE THE PLACE FOR US ALL. Every man amongst us has to go down there, if we take the place that belongs to us.
II. UNLESS YOU HAVE CRIED TO GOD OUT OF THOSE DEPTHS, YOU HAVE NEVER CRIED TO HIM AT ALL. Unless you come to him as a penitent, sinful man, with the consciousness of transgression awakened within you, your prayers are shallow. The beginning of all true personal religion lies in the sense of my own sin and my lost condition. Whenever you find men and women with a Christianity that sits very lightly upon them, that does not impel them to any acts of service and devotion, and never rises into the heights of communion with God, depend upon it the man has never been down into the abyss, and never sent his voice up from it. "Out of the depths" he has not cried unto God.
III. YOU WANT NOTHING MORE THAN A CRY TO DRAW YOU FROM THE PIT. It is not that your crying will lift you out; it is that your crying will bring you help. The "infant crying in the night" does nothing for itself by its crying; but the cry brings its mother. And the cry means that hope of self-help is altogether abandoned, the soul having to say, "Myself I cannot save," cries after Christ, saying, "Jesu, have mercy on me!" (part Maclaren).—R.T.
