The psalm is remarkable for the abrupt transition of feeling which cleaves it into two parts; one (vers. 1-6) full of jubilant hope and enthusiastic faith, the other (vers. 7-14) a lowly cry for help. There is no need to suppose, with some critics, that we have here two independent hymns bound together in error. He must have little knowledge of the fluctuations of the devout life who is surprised to find so swift a passage from confidence to conscious weakness. Whilst the usual order in the psalms, as the usual order in good men's experience, is that prayer for deliverance precedes praise and triumph, true communion with God is bound to no mechanical order, and may begin with gazing on God, and realizing the mysteries of beauty in His secret place, ere it drops to earth. The lark sings as it descends from the "privacy of glorious light" to its nest in the stony furrows as sweetly, though more plaintively, than whilst it circles upwards to the sky. It is perhaps a nobler effect of faith to begin with God and hymn the victory as if already won, than to begin with trouble and to call for deliverance. But with whichever we commence, the prayer of earth must include both; and so long as we are weak, and God our strength, its elements must be "supplication and thanksgiving." The prayer of our psalm bends round again to its beginning, and after the plaintive cry for help breaks once more into confidence (vers. 13, 14). The psalmist shudders as he thinks what ruin would have befallen him if he had not trusted in God, and leaves the unfinished sentence,--as a man looking down into some fearful gulf starts back and covers his eyes, before he has well seen the bottom of the abyss. "If I had not believed to see the goodness of the Lord in the land of the living!" Then rejoicing to remember how even by his feeble trust he has been saved, he stirs up himself to a firmer faith, in words which are themselves an exercise of faith, as well as an incitement to it: "Wait on Jehovah! Courage! and let thy heart be strong! Yea! wait on Jehovah!" Here is the true highest type of a troubled soul's fellowship with God, when the black fear and consciousness of weakness is inclosed in a golden ring of happy trust. Let the name of our God be first upon our lips, and the call to our wayward hearts to wait on Him be last, and then we may between think of our loneliness, and feebleness, and foes, and fears, without losing our hold of our Father's hand.
