Numbers 19:17-22

See, Reader, in the typical representation of this law, what a gracious provision is made, for the removal of the uncleanness of our fallen nature. As the ashes of the heifer pointed to the atonement and righteousness of JESUS: so the running water represented the precious offices of the HOLY GHOST, in the washing of regeneration, and a renewing of our souls by his grace; that by his gracious application of the person and offices of the LORD JESUS, souls might be made clean in the sight of GOD, and our FATHER. Reader! do not overlook in this scripture, the essential offices of both. The ashes not mixed with the running water were not used, nor could be efficacious. Neither do the merits of JESUS operate on your heart or mine, unless applied by the HOLY GHOST. So vast and infinitely important is the work of GOD upon the soul, since it is he alone, which must take of the things of JESUS, and show them unto us. See the Redeemer's own account of his important office and ministry, in what he hath said of his person, and offices, and character. John 16:7.
