Charles H. Spurgeon on Psalms 119:140

Thy word is very pure; therefore, etc. The word of God is not only "pure, "free from all base admixture, but it is a purifier;it cleanses from sin and guilt every heart with which into comes into contact. "Now ye are clean, "said Jesus Christ to his disciples, "by the word which I have spoken unto you": John 15:3. It is this its pure quality combined with its tendency to purify every nature that yields to its holy influence, that endears it to every child of God. Here it is that he finds those views of the divine character, those promises, those precepts, those representations of the deformity of sin, of the beauty of holiness, which lead him, above all things, to seek conformity to the divine image. A child of God in his best moments does not wish the word of God brought down to a level with his own imperfect character, but desires rather that his character may be gradually raised to a conformity to that blessed word. Because it is altogether pure, and because it tends to convey to those who make it their constant study a measure of its own purity, the child of God loves it, and delights to meditate in it day and night. John Morison.
