Some facts need more evidence than others, we know. This is true of the fact of the existence of God. But the Bible history is sufficient to satisfy every reasonable demand. The history of the Jews, prophecy, is not explainable minus God. If we cannot believe in the existence of God on the testimony of the Bible we might as well burn our books of history. A man cannot deny the truth of the testimony of the Bible unless he says plainly: "No amount of testimony will convince me of the supernatural." Scripture does not attempt to prove the existence of God; it asserts, assumes, and declares that the knowledge of God is universal, Rom. 1:19-21, 28, 33; 2:15. It asserts that God has wrought this great truth in the very warp and woof of every man's being, so that nowhere is He without this witness. The preacher may, therefore, safely follow the example of the Scripture in assuming that there is a God. Indeed he must unhesitatingly and explicitly assert it as the Scripture does, believing that "His eternal power and divinity" are things that are clearly seen and perceived through the evidences of His handiwork which abound on every hand. II. THE NATURE OF GOD: (Vs. Agnosticism). 1. THE SPIRITUALITY OF GOD: (Vs. Materialism). "GOD IS SPIRIT." a) Statement of the Fact, John 4:24: "God is Spirit." Meaning: The Samaritan woman's question, "Where is God to be found?" etc. On Mt. Zion or Gerizim? Christ's answer: God is not to be confined to any one place (cf. Acts 7:48; 17:25, 1 Kings 8:27). God must be worshipped _in spirit_ as distinguished from place, form, or other sensual limitations (4:21); and _in truth_ as distinguished from false conceptions resulting from imperfect knowledge (4:22). b) Light on "God is Spirit," from other Scriptures. Luke 24:39: "A spirit hath not flesh and bones," i. e., has not body, or parts like human beings; incorporeal; not subject to human limitations. Col. 1:15: "The image of the invisible God." 1 Tim. 1:17 (R. V.): "Now unto the King incorruptible, invisible." These passages teach that God has nothing of a material or bodily nature. Sight sees only objects of the material world, but God is not of the nature of the material world, hence He cannot be seen with the material eye--at least not now. c) Light Derived from Cautions Against Representing God by Graven Images: Deut. 4:15-23; Isa. 40:25; Exod. 20:4. Study these passages carefully and note that the reason why images were forbidden was because no one had ever seen God, and consequently could not picture how He looked, and, further, there was nothing on the earth that could resemble Him. d) Definition of "God is Spirit" in the Light of All This:
