It is not enough, then, to be a creature of God, to be born of the flesh, or of the will of man. The soul who would receive the Holy Ghost, to see and have God in His fulness, must be born of God. "Except a man be born of water and the Holy Ghost, he cannot enter into the kingdom of God." [Footnote 31] As the Son of God became incarnate by the Holy Ghost of the Virgin, so the sons of men must be born again of water and the Holy Ghost in Baptism, to become the sons of God. Then, and then only, can we call God Father. Then, and then only, do we "receive the spirit of adoption of sons," as St. Paul declares, "whereby we cry, Abba (Father)." [Footnote 32] We must believe in the Word made flesh, in Jesus Christ, else that other Comforter will not come unto us; and hence the Church invokes the Holy Ghost to come down into the hearts of the __faithful__, or the believers in Jesus Christ. [Footnote 31: Ibid. iii. 5.] [Footnote 32: Rom. viii. 15.] {111} "Come, O Holy Spirit! fill the hearts of thy faithful, and kindle in them the fire of thy love." Alas! for those who do not realize this great truth. By their rejection of Jesus Christ and the new birth unto God in Baptism, they remain for ever in the lower sphere of the simple creature, with no hope of the enrapturing vision of the Blessed Trinity when their souls shall have passed beyond this human life, in which the choice of that higher destiny is given to them. This is the first thought suggested to us by the opening invocation of the sequence of the Mass. And now the sentiment of the sequence suddenly changes. Though we be so exalted by the Divine relationship, though the light of Heaven's glory is beaming upon our footsteps as we advance towards it, and our loosened tongues cry out with St. Paul, "O the depth of the riches of the wisdom and of the knowledge of God!" [Footnote 33] yet what is our human life now compared with the Heavenly Life in God! It is a blessed truth to me, some of us say, and a hope that I would not part with for life; but though inexhaustible riches, and crowns and harps of gold, are waiting for me in the kingdom of the Heavenly Father, here I am poor, here my heart is too sad to sing. [Footnote 33: Rom. xi. 33.] {112} Though there I shall possess wisdom, to which the wisdom of this world is foolishness, yet here I am ignorant. There shall be no want, I know; but here I am ever in want. I cry, Give, give, and my soul is never satisfied. There, in the light of glory, shall be peace, rest, and victory; but here is toil, strife, temptation, defeat, and my heart is oft darkened within me, even to forget my God. Hark what the Holy Church inspires you to say: "Veni, Sancte Spiritus, Veni, Pater pauperum, Veni, dator munerum, Veni, lumen cordium!" "Come, O Holy Spirit! Come, O Father of the poor! Come, O giver of every gift! Come, O light of every heart!"
