This baptism, too, was to be so searching as to be able to penetrate the hardest heart, and to make even the Gentiles the real children of Abraham.[148] "For think not, says John, in allusion to the same baptism, to say within yourselves, we have Abraham to our Father; for I say unto, you, that God is able of these stones to raise up children unto Abraham." As if he had said, I acknowledge that you Pharisees can, many of you, boast of relationship to Abraham by a strict and scrupulous attention to shadowy and figurative ordinances; that many of you can boast of relationship to him by blood; and all of you by circumcision. But it does not follow, therefore, that you are the children of Abraham. Those only will be able to boast of being his seed, to whom the fan and fire of Christ's baptism shall be applied. The baptism of him, who is to come after me, and whose kingdom is at hand, is of that spiritual and purifying nature, that it will produce effects very different from those of an observance of outward ordinances. It can so cleanse and purify the hearts of men, that if there are Gentiles in the most distant lands, ever so far removed from Abraham, and possessing hearts of the hardness of stones, it can make them the real children of Abraham in the sight of God. [Footnote 148: Math. 3.9.] This distinction between the watery baptism of John, and the fiery and spiritual baptism of Christ, was pointed out by Jesus Christ himself; for, he is reported to have appeared to his disciples after his resurrection, and to have commanded them [149] "that they should not depart from Jerusalem, but wait for the promise of the Father, which, says he, ye have heard from me. For John truly baptized with water, but ye shall be baptized with the Holy Ghost not many days hence." [Footnote 149: Acts 1.4.] Saint Luke also records a transaction which took place, in which Peter was concerned, and on which occasion he first discerned the baptism of Christ, as thus distinguished in the words which have been just given. [150] "And as I began to speak, says he, the Holy Ghost fell on them, as on us at the beginning. Then remembered I the word of the Lord, how that he said, John, indeed, baptised with water, but ye shall be baptized by the Holy Spirit." [Footnote 150: Acts II, 15,16.] A similar distinction is made also by St. Paul; for when he found that certain disciples had been baptized only with the baptism of John,[151] he laid his hand upon them, and baptized them again; but this was with the baptism of the spirit. In his epistle also, to the Corinthians, we find the following expression:[152] "For by one spirit are we all baptized unto one body." [Footnote 151: Acts 19.] [Footnote 152: I Cor. 12, 13]. SECT. III.
