Wash me, and I shall be whiter than snow. – Psalm 51:7

What a beautiful sight it was, this morning, when we looked out, and saw the ground all covered with snow! The trees were all robed in silver; yet it is almost an insult to the snow to compare it to silver, for silver at its brightest is not worthy to be compared with the marvelous splendour that was to be seen wherever the trees appeared adorned with beautiful festoons above the earth which was robed in its pure white mantle. If we had taken a piece of what we call white paper, and laid it down upon the surface of newly-fallen snow, it would have seemed quite begrimed in comparison with the spotless snow. This morning’s scene at once called the text to my mind: “Wash me, and I shall be whiter than snow.” You, O black sinner, if you believe in Jesus, shall not only be washed in His precious blood until you become tolerably clean, but you shall be made white, yea, you shall be “whiter than snow.” When we have gazed upon the pure whiteness of the snow before it has become defiled, it has seemed as though there could be nothing whiter. I know that, when I have been among the Alps, and have for hours looked upon the dazzling whiteness of the snow, I have been almost blinded by it. If the snow were to lie long upon the ground, and if the whole earth were to be covered with it, we should soon all be blind. The eyes of man have suffered with his soul through sin, and just as our soul would be unable to bear a sight of the unveiled purity of God, our eyes cannot endure to look upon the wondrous purity of the snow. Yet the sinner, black through sin, when brought under the cleansing power of the blood of Jesus, becomes “whiter than snow.” ~ C.H. Spurgeon
