"There is a fountain filled with blood Drawn from Emanuel's veins, And sinners plunged beneath that flood Lose all their guilty stains." The fountain was indeed in existence throughout all the long centuries of Israel's dispersion. But Israel in blindness did not see it, only the remnant according to the election of grace did realize the precious blood of the Lamb of God, which has taken away the sins of the world. Now all is changed. Upon the inhabitants of Jerusalem and the house of David the Spirit is poured out. They have seen Him who is the first-born among many brethren, the second Adam, the One who is the Head of a new creation, and the blood of Him, the Lord Jesus Christ, is now cleansing them from all sin and uncleanness. Their guilt is pardoned and all unrighteousness and impurity is completely removed. This great event is everywhere spoken of in the Old Testament. We had it under consideration in the third chapter, containing the night vision of the cleansing of Joshua, the High priest. In that vision the blood which cleanses was not mentioned. Now, however, it is seen, that the cleansing is by the blood of the Lamb. It is the same precious blood which cleansed and washed the glorified saints. The great multitude, which no man can number, out of every nation and of all tribes and peoples and tongues; the saints arrayed in white robes with palms in their hands, who washed their robes in the blood of the Lamb, and who appear with Him. And while they sing their song of praise, Salvation unto our God which sitteth on the throne and unto the Lamb, Israel will be washed by the same blood and join into the song of worship heard from the glorified lips of the saints of God. In the 103d Psalm we have a prophetic expression of what Israel will rejoice in when that fountain is opened. The cleansed nation will break forth and sing: "Bless Jehovah, oh my soul, And all that is within me bless His holy name; Bless Jehovah, oh my soul, and forget not all His benefits. Who forgiveth all thine iniquities, Who healeth all thy diseases, Who reedeemeth thy life from destruction, Who crowneth thee with lovingkindness and tender mercies."
