And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. -Genesis 1:2

Acts and deeds are ascribed to the Holy Ghost; therefore, He must be a person. You read in the first chapter of the Book of Genesis, that the Spirit brooded over the surface of the earth, when it was as yet all disorder and confusion. This world was once a mass of chaotic matter, there was no order; it was like the valley of darkness and of the shadow of death. God the Holy Ghost spread His wings over it; He sowed the seeds of life in it; the germs from which all beings sprang were implanted by Him; He impregnated the earth so that it became capable of life. Now, it must have been a person who brought order out of confusion: it must have been an existence who hovered over this world and made it what it now is. But do we not read in Scripture something more of the Holy Ghost? Yes, we are told that “holy men of old spake as they were moved by the Holy Ghost.” When Moses penned the Pentateuch, the Holy Ghost moved his hand; when David wrote the Psalms, and discoursed sweet music on his harp, it was the Holy Spirit that gave his fingers their seraphic motion; when Solomon dropped from his lips the words of the proverbs of wisdom, or when he hymned the Canticles of love, it was the Holy Ghost who gave him words of knowledge and hymns of rapture. Ah! and what fire was that which touched the lips of the eloquent Isaiah? What hand was that which came upon Daniel? What might was that which made Jeremiah so plaintive in his grief? or what was that which winged Ezekiel and made him like an eagle, soar into mysteries aloft, and see the mighty unknown beyond our reach? Who was it that made Amos, the herdsman, a prophet? Who taught the rugged Haggai to pronounce his thundering sentences? Who showed Habakkuk the horses of Jehovah marching through the waters? or who kindled the burning eloquence of Nahum? Who caused Malachi to close up the book with the muttering of the word curse? Who was it in each of these, save the Holy Ghost? And must it not have been a person who spake in and through these ancient witnesses? We must believe it. We cannot avoid believing it, when we read that “holy men of old spake as they were moved by the Holy Ghost.” ~ C.H. Spurgeon
