If we regard this second verse of our text as the expression of the Psalmist's emotion at the moment of its utterance, then we see in it a beautiful illustration of the effect of faithful waiting to turn complaining into praise. If we regard it rather as an expression of his confidence, that 'I shall yet praise Him for the help of His countenance,' we see in it an illustration of the power of patient waiting to brighten the sure hope of deliverance, and to bring summer into the heart of winter. As resolve, or as prophecy, it is equally a witness of the large reward of quiet waiting for the salvation of the Lord.
In either application of the words their almost precise correspondence with those of the previous verse is far more than a mere poetic ornament, or part of the artistic form of the psalm. It teaches us this happy lesson--that the song of accomplished deliverance, whether on earth, or in the final joy of heaven, will be but a sweeter, fuller repetition of the cry that went up in trouble from our waiting hearts. The object to which we shall turn with our thankfulness is He to whom we betook ourselves with our prayers. There will be the same turning of the soul to Him; only instead of wistful waiting in the longing look, joy will light her lamps in our eyes, and thankfulness beam in our faces as we turn to His light. We shall look to Him as of old, and name Him what we used to name Him when we were in weakness and warfare,--our 'Strength' and our 'Defence.' But how different the feelings with which the delivered soul calls Him so, from those with which the sorrowful heart tried to grasp the comfort of the names. Then their reality was a matter of faith, often hard to hold fast. Now it is a matter of memory and experience. 'I called Thee my strength when I was full of weakness; I tried to believe Thou wast my defence when I was full of fear; I thought of Thee as my fortress when I was ringed about with foes; I know Thee now for that which I then trusted that Thou wast. As I waited upon Thee that Thou mightest be gracious, I praise Thee now that Thou hast been more gracious than my hopes.' Blessed are they whose loftiest expectations were less than their grateful memories and their rich experience, and who can take up in their song of praise the names by which they called on God, and feel that they knew not half their depth, their sweetness, or their power!
But the praise is not merely the waiting transformed. Experience has not only deepened the conception of the meaning of God's name; it has added a new name. The cry of the suppliant was to God, his strength and defence; the song of the saved is to the God who is also the God of his mercy. The experiences of life have brought out more fully the love and tender pity of God. While the troubles lasted it was hard to believe that God was strong enough to brace us against them, and to keep us safe in them; it was harder still to think of them as coming from Him at all; it was hardest to feel that they came from His love. But when they are past, and their meaning is plainer, and we possess their results in the weight of glory which they have wrought out for us, we shall be able to look back on them all as the mercies of the God of our mercy, even as when a man looks down from the mountain-top upon the mists and the clouds through which he passed, and sees them all smitten by the sunshine that gleams upon them from above. That which was thick and damp as he was struggling through it, is irradiated into rosy beauty; the retrospective and downward glance confirms and surpasses all that faith dimly discerned, and found it hard to believe. Whilst we are fighting here, brethren! let us say, 'I will wait for Thee,' and then yonder we shall, with deeper knowledge of the love that was in all our sorrows, sing unto Him who was our strength in earth's weakness, our defence in earth's dangers, and is for ever more the 'God of our mercy,' amidst the large and undeserved favours of heaven.
