Charles H. Spurgeon on Psalms 119:55

I have remembered thy name, O Lord, in the night. This verse contains a new protestation of his honest affection toward the word of God. Wherein, first, let us mark his sincerity; he was religious not only in public, but in private; for private exercises are the surest trials of true religion. In public, oftentimes hypocrisy carries men to simulate that which they are not; it is not so in the private devotion; for then, either doth a man, if he make no conscience of God's worship, utterly neglect it, because there is no eye of man to see him; or otherwise if he be indeed religious, even in private he presents his heart to God, seeking it to be approved by him; for his "praise is not of man, but of God."

Again, this argues his fervency in religion: for as elsewhere he protests that he loved the word more than his appointed food; so here he protests that he gave up his night's rest that he might meditate in the word. But now, so far is zeal decayed in professors, that they will not forego their superfluities, far less their needful refreshment, for love of the word of God. William Cowper.
