As to the fact of the continual relapses into idolatry, nothing could be more natural than that the recently received and but imperfectly assimilated revelation of the one God, with its stringent requirements of purity, and its severe prohibition of idols, should easily slip off from these rude and merely outward worshippers. Joshua's death without a successor, the dispersion of the tribes, the difficulty of communication when much of the country was still in the hands of its former possessors, would all weaken the sense of unity, which was too recent to be firm, and would expose the isolated Israelites to the full force of the temptation to idolatry. It is difficult for us fairly to judge the immense strain required for resistance to it. The conception of one sole God was too high to be easily retained. A shrine without a deity seemed bare and empty. The Law stringently bridled passions which the hideous worship of the Canaanites stimulated. No wonder that, when the first generation of the conquerors had passed away, their successors lapsed into the universal polytheism, with its attendant idolatry and immorality. Instead of thinking of the Israelites as monsters of ingratitude and backsliding, we come nearer the truth, and make a better use of the history, when we see in it a mirror which shows us our own image. The strong earthward pull is ever acting on us, and, unless God hold us up, we too shall slide downwards. 'Hath a nation changed their gods, which yet are no gods? but My people hath changed their glory for that which doth not profit.' Idolatry and worldliness are persistent; for they are natural. Firm adherence to God is less common, because it goes against the strong forces, within and without, which bind us to earth. Apparently the relapses into idolatry did not imply the entire abandonment of the worship of Jehovah, but the worship of Baalim and Ashtaroth along with it. Such illegitimate mixing up of deities was accordant with the very essence of polytheism, and repugnant to that of the true worship of God. The one may be tolerant, the other cannot be. To unite Baal with Jehovah was to forsake Jehovah. These continual relapses have an important bearing on the question of the origin of the 'Jewish conception of God.' They are intelligible only if we take the old-fashioned explanation, that its origin was a divine revelation, given to a rude people. They are unintelligible if we take the new-fashioned explanation that the monotheism of Israel was the product of natural evolution, or was anything but a treasure put by God into their hands, which they did not appreciate, and would willingly have thrown away. The foul Canaanitish worship was the kind of thing in which, if left to themselves, they would have wallowed. How came such people by such thoughts as these? The history of Israel's idolatry is not the least conclusive proof of the supernatural revelation which made Israel's religion.
