It is not given to many men to add new words to the vocabulary of religious emotion. But so far as an examination of the Old Testament avails, I find that David was the first that ever employed the word that is here translated, _I will trust_, with a religious meaning. It is found occasionally in earlier books of the Bible in different connections, never in regard to man's relations to God, until the Poet-Psalmist laid his hand upon it, and consecrated it for all generations to express one of the deepest relations of man to his Father in heaven. And it is a favourite word of his. I find it occurs constantly in his psalms; twice as often, or nearly so, in the psalms attributed to David as in all the rest of the Psalter put together; and as I shall have occasion to show you in a moment, it is in itself a most significant and poetic word. But, first of all, I ask you to notice how beautifully there comes out here the _occasion_ of trust. 'What time I am afraid, I will put my trust in Thee.' This psalm is one of those belonging to the Sauline persecution. If we adopt the allocation in the superscription, it was written at one of the very lowest points of David's fortunes. And there seem to be one or two of its phrases which acquire new force, if we regard the psalm as drawn forth by the perils of his wandering, hunted life. For instance--'Thou tellest my wanderings,' is no mere expression of the feelings with which he regarded the changes of this early pilgrimage, but is the confidence of the fugitive that in the doublings and windings of his flight God's eye marked him. 'Put thou my tears into Thy _bottle_'--one of the few indispensable articles which he had to carry with him, the water-skin which hung beside him, perhaps, as he meditated. So read in the light of his probable circumstances, how pathetic and eloquent does that saying become--'What time I am afraid, I will trust in Thee.' That goes deep down into the realities of life. It is when we are 'afraid' that we trust in God; not in easy times, when things are going smoothly with us. Not when the sun shines, but when the tempest blows and the wind howls about his ears, a man gathers his cloak round him, and cleaves fast to his supporter. The midnight sea lies all black; but when it is cut into by the oar, or divided and churned by the paddle, it flashes up into phosphorescence, and so it is from the tumults and agitation of man's spirit that there is struck out the light of man's faith. There is the bit of flint and the steel that comes hammering against it; and it is the contact of these two that brings out the spark. The man never knew confidence who does not know how the occasion that evoked and preceded it was terror and need. 'What time I am _afraid_, I will trust.' That is no trust which is only fair weather trust. This principle--first fear, and only then, faith--applies all round the circle of our necessities, weaknesses, sorrows, and sins.
