A well-known modern scientist has hazarded the speculation that the origin of life on this planet has been the falling upon it of the fragments of a meteor, or an aerolite from some other system, with a speck of organic life upon it, from which all has developed. Whatever may be the case in regard to physical life, that is absolutely true in the case of spiritual life. It all originates because this heaven-descended Christ has come down the long staircase of Incarnation, and has brought with Him into the clouds and oppressions of our terrestrial atmosphere a germ of life which He has planted in the heart of the race, there to spread for ever. That is the measure of the depth of the love of Christ. And there is another way to measure it. My sins are deep, my helpless miseries are deep, but they are shallow as compared with the love that goes down beneath all sin, that is deeper than all sorrow, that is deeper than all necessity, that shrinks from no degradation, that turns away from no squalor, that abhors no wickedness so as to avert its face from it. The purest passion of human benevolence cannot but sometimes be aware of disgust mingling with its pity and its efforts, but Christ's love comes down to the most sunken. However far in the abyss of degradation any human soul has descended, beneath it are the everlasting arms, and beneath it is Christ's love. When a coalpit gets blocked up by some explosion, no brave rescuing party will venture to descend into the lowest depths of the poisonous darkness until some ventilation has been restored. But this loving Christ goes down, down, down into the thickest, most pestilential atmosphere, reeking with sin and corruption, and stretches out a rescuing hand to the most abject and undermost of all the victims. How deep is the love of Christ! The deep mines of sin and of alienation are all undermined and countermined by His love. Sin is an abyss, a mystery, how deep only they know who have fought against it; but 'O love! thou bottomless abyss, My sins are swallowed up in thee.' 'I will cast all their sins into the depths of the sea.' The depths of Christ's love go down beneath all human necessity, sorrow, suffering, and sin. IV. And lastly, what is the height of the love of Christ?
