Charles H. Spurgeon on Psalms 119:82

Mine eyes fail for thy word, saying, When wilt thou comfort me? His eyes gave out with eagerly gazing for the kind appearance of the Lord, while his heart in weariness cried out for speedy comfort. To read the word till the eyes can no longer see is but a small thing compared with watching for the fulfilment of the promise till the inner eyes of expectancy begin to grow dim with hope deferred. We may not set times to God, for this is to limit the Holy One of Israel; yet we may urge our suit with importunity, and make fervent enquiry as to why the promise tarries. David sought no comfort except that which comes from God; his question is, "When wilt thou comfort me?" If help does not come from heaven it will never come at all: all the good man's hopes look that way, he has not a glance to dart in any other direction. This experience of waiting and fainting is well known by full grown saints, arid it teaches them many precious lessons which they would never learn by any other means. Among the choice results is this one that the body rises into sympathy with the soul, both heart and flesh cry out for the living God, and even the eyes find a tongue, "saying, When wilt thou comfort me?" It must be an intense longing which is not satisfied to express itself by the lips, but speaks with the eyes, by those eyes failing through intense watching. Eyes can speak right eloquently; they use both mutes and liquids, and can sometimes say more than tongues. David says in another place, "The Lord hath heard the voice of my weeping" (Psalms 6:8). Specially are our eyes eloquent when they begin to fail with weariness and woe. A humble eye lifted up to heaven in silent prayer may flash such flame as shall melt the bolts which bar the entrance of vocal prayer, and so heaven shall be taken by storm with the artillery of tears. Blessed are the eyes that are strained in looking after God. The eyes of the Lord will see to it that such eyes do not actually fail. How much better to watch for the Lord with aching eyes than to have them sparkling at the glitter of vanity.
