If men were true to this commandment, obedience to the remaining nine would follow naturally. It is because they are unsound in this that they break the others. FEELING AFTER GOD. Philosophers are agreed that even the most primitive races of mankind reach out beyond the world of matter to a superior Being. It is as natural for man to feel after God as it is for the ivy to feel after a support. Hunger and thirst drive him to seek for food, and there is a hunger of the soul that needs satisfying, too. Man does not need to be commanded to worship, as there is not a race so high or so low in the scale of civilization but has some kind of a god. What he needs is to be directed aright. This is what the first commandment is for. Before we can worship intelligently, we must know what or whom to worship. God does not leave us in ignorance. When Paul vent to Athens, he found an altar dedicated to "An Unknown God," and he proceeded to tell of Him whom we worship. When God gave the commandments to Moses, He commenced with a declaration of His own character, and demanded exclusive recognition. "I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods before me." The Rev. Dr. Dale says these words have great significance. "The Jews knew Jehovah as the God who had held back the waves like a wall while they fled across the sea to escape the vengeance of their enemies; they knew him as the God who had sent thunder, and lightning, and hail, plagues on cattle, and plagues on men, to punish the Egyptians and to compel them to let the children of Israel go; they knew Him as the God whose angel had slain the firstborn of their oppressors, and filled the land from end to end with death, and agony, and terror. He was the same God, so Moses and Aaron told them, who by visions and voices, in promises and precepts, had revealed Himself long before to Abraham, Isaac, and Jacob. We learn what men are from what they say and from what they do. A biography of Luther gives a more vivid and trustworthy knowledge of the man than the most philosophical essay on his character and creed. The story of his imprisonment and of his journey to Worms, his Letters, his Sermons, and his Table-Talk, are worth more than the most elaborate speculations about him. The Jews learned what God is, not from theological dissertations on the Divine attributes, but from the facts of a Divine history. They knew Him for themselves in His own acts and His own words." Some one asked an Arab: "How do you know that there is a God?" "How do I know whether a man or a camel passed my tent last night?" he replied. God's footprints in nature and in our own experience are the best evidence of His existence and character. THE ISRAELITES WERE EXPOSED TO DANGER.
