The deep undertone of the world is sadness - a solemn bass, occurring at measured intervals and heard through all other tones. Ultimately, all the strains of this world's music resolve themselves into that tone; and I believe that, rightly felt, the cross, and the cross alone, interprets the mournful mystery of life, the sorrow of the Highest - the Lord of Life, the result of error and sin, but ultimately remedial, purifying and exalting.
