Jesus Christ, the ever-living Son of God, is the one supreme answer to the restlessness and travail of our day. But he cannot, he will not reveal himself. Each person in the Holy Trinity reveals another. The Son reveals the Father, but his own revelation awaits the testimony of the Holy Ghost, which, though often given directly, is largely through the church. What we need then, and what the world is waiting for, is the Son of God, borne witness to and revealed in all his radiant {xii} beauty of the ministry of the Holy Spirit, as he energizes with and through the saints that make up the holy and mystical body, the church. It is needful to emphasize this distinction. In some quarters it seems to be supposed that the Holy Spirit himself is the solution of the perplexities of our time. Now what we may witness in some coming age we know not, but in this it is clear that God in the person of Christ is the one only and divine answer. Here is God's yea and amen, the Alpha and Omega, sight for the blind, healing for the paralyzed, cleansing for the polluted, life for the dead, the gospel for the poor and sad and comfortless. Now we covet the gracious bestowal of the Spirit, that he may take more deeply of the things of Christ, and reveal them unto us. When the disciples sought to know the Father, the Lord said, He that hath seen me hath seen the Father. It is his glory that shines on my face, his will that molds my life, his purpose that is fulfilled in my ministry. So the blessed Paraclete would turn our thought and attention from himself to him, with whom he is One in the Holy Trinity, and whom he has come to reveal. {xiii} Throughout the so-called Christian centuries the voice of the Holy Spirit has borne witness to the Lord, directly and mediately. Directly, in each widespread quickening of the human conscience, in each revival of religion, in each era of advance in the knowledge of divine truth, in each soul that has been regenerated, comforted, or taught. Mediately his work has been carried on through the church, the body of those that believe. But, alas! how sadly his witness has been weakened and hindered by the medium through which it has come. He has not been able to do many mighty works because of the unbelief which has kept closed and barred those avenues through which he would have poured his glad testimony to the unseen and glorified Lord. The divisions of the church, her strife about matters of comparative unimportance, her magnification of points of difference, her materialism, her love of pelf and place and power, her accounting herself rich and increased in goods and needing nothing, when she was poor, and miserable, and blind, and naked--these things have not only robbed her of her testimony, but have grieved and {xiv} quenched the Holy Spirit, and nullified his testimony.
