We have seen, in the prophecy of Isaiah, the source whence the figure of sprinkling or pouring is derived. “I will pour water upon him that is thirsty, and floods upon the dry ground; I will pour my Spirit upon thy seed, and my blessing upon thine offspring; and they shall spring up as among the grass, as willows by the water courses.”—Isa. xliv, 3, 4. It is the descent of the rain from heaven, penetrating the earth, and converting its deadness into life, abundance, and beauty. Herein the rites in question stand in beautiful contrast with the self-washings of the law. The latter accomplished a surface cleansing, by a process which neither could, nor was designed to penetrate the substance, or to affect its essential state or nature. They indicated to God’s people the duty of conforming the external life to the grace wrought in the heart by the Holy Spirit. But the rite of sprinkling represented the rain of God, sent down from heaven, penetrating the soil, pervading and saturating it, converting its hard, dead, and sterile clods into softness, life, and fertility, and causing the plants and fruits of the earth to spring forth, saturated with the same moisture, and thus possessed and pervaded with the same spirit of life. Thus was typified the work of the Spirit, entering, pervading, and softening the stony heart, converting all its powers and faculties as instruments of holiness to God, and causing the plants of righteousness to spring up and grow in the life and conduct. The two words, _sprinkle_, and _pour_, are used throughout the Scriptures with reference to the same figure of rain, the only apparent difference being that the word, pour, expresses the idea of abundance. No phenomenon of nature is of greater manifest importance, or more pervasive and vital in its influences than the rain of heaven, and none more suitable to illustrate the method of grace. The land from which the rains are withheld is without fruit, or beauty, or attraction. It is given over to barrenness, death, and cursing; and, in the language of the Scriptures, is accounted unclean, as being shut out from the favor of God, whose favor is life. Hence, the word of God, to the prophet, concerning Israel: “Son of man, say unto her, Thou art the land that is not _cleansed_, nor _rained upon_, in the day of indignation.”—Ezek. xxii, 24. Similar is the significance of our Savior’s words: “When the unclean spirit is gone out of a man, he walketh through dry places” (_anhudrōn topōn_, “waterless places”), places congenial to him because unblessed with the Spirit’s presence. (Matt. xii, 43; Luke xi, 24.)
