This man's profession of utter resignation is perhaps too high for us; but we can make his _self-exhortation_ our own. 'My soul! wait thou only upon God.' Perfect as he ventures to declare his silence towards God, he yet feels that he has to stir himself up to the effort which is needed to preserve it in its purity. Just because he can say, 'My soul waits,' therefore he bids his soul wait.
I need not dwell upon that self-stimulating as involving the great mystery of our personality, whereby a man exalts himself above himself, and controls, and guides, and speaks to his soul. But a few words may be given to that thought illustrated here, of the necessity for conscious effort and self-encouragement, in order to the preservation of the highest religious emotion.
We are sometimes apt to forget that no holy thoughts or feelings are in their own nature permanent, and the illusion that they are so, often tends to accelerate their fading. It is no wonder if we in our selectest hours of 'high communion with the living God' should feel as if that lofty experience would last by virtue of its own sweetness, and need no effort of ours to retain it. But it is not so. All emotion tends to exhaustion, as surely as a pendulum to rest, or as an Eastern torrent to dry up. All our flames burn to their extinction. There is but one fire that blazes and is not consumed. Action is the destruction of tissue. Life reaches its term in death. Joy and sorrow, and hope and fear, cannot be continuous. They must needs wear themselves out and fade into a grey uniformity like mountain summits when the sun has left them.
Our religious experience too will have its tides, and even those high and pure emotions and dispositions that bind us to God can only be preserved by continual effort. Their existence is no guarantee of their permanence, rather is it a guarantee of their transitoriness, unless we earnestly stir up ourselves to their renewal. Like the emotions kindled by lower objects, they perish while they glow, and there must be a continual recurrence to the one Source of light and heat if the brilliancy is to be preserved.
Nor is it only from within that their continuance is menaced. Outward forces are sure to tell upon them The constant wash of the sea of life undermines the cliffs and wastes the coasts. The tear and wear of external occupations is ever acting upon our religious life. Travellers tell us that the constant friction of the sand on Egyptian hieroglyphs removes every trace of colour, and even effaces the deep-cut characters from basalt rocks. So the unceasing attrition of multitudinous trifles will take all the bloom off your religion, and efface the name of the King cut on the tables of your hearts, if you do not counteract them by constant earnest effort. Our devotion, our faith, our love are only preserved by being constantly renewed.
That vigorous effort is expressed here by the very form of the phrase. The same word which began the first clause begins the second also. As in the former it represented for us, with an emphatic 'Truly,' the struggle through which the Psalmist had reached the height of his blessed experience, so here it represents in like manner the earnestness of the self-exhortation which he addresses to himself. He calls forth all his powers to the conflict, which is needed even by the man who has attained to that height of communion, if he would remain where he has climbed. And for us, brethren! who shrink from taking these former words upon our lips, how much greater the need to use our most strenuous efforts to quiet our souls. If the summit reached can only be held by earnest endeavour, how much more is needed to struggle up to it from the valleys below!
