“Visiting iniquity” and “showing mercy” are set over against each other――the penal visitations of judgment for this sin warning men against it; and the great promises of mercy to the obedient alluring them to its most diligent observance. Judgment is God’s strange work, while mercy is his delight. Therefore we have here the forceful antithesis――the visiting of the iniquities of fathers upon children to the third and fourth generation, but the showing of mercy unto thousands of generations of them that love and obey. To a Hebrew mind this last clause of the second command would naturally suggest God’s mercies to Abraham, the well-known friend of God, upon whose posterity God was shedding forth his blessings to thousands of generations. So richly does the loving God reward his dutiful and trustful children! So much more grateful to his heart it is to bless even to the thousandth generation than to visit iniquity even so far as to the third and fourth! It should be carefully noted that the visiting of the iniquities of fathers upon sons falls only _upon those who hate him_. If sons in any future generation turn from their sinning to the love of God, his merciful loving-kindness to them is sure. The curse visits only those who persist in the sin of their fathers despite of all the warning judgments that should admonish them to fear God. (See Ezek. 18).――――This injunction against image-making and worship would naturally suggest to the men of Israel the idolatrous Egyptians. Their early fathers received from Noah the knowledge of the one only true God. But they did not love this knowledge, nor the God whom it revealed; therefore, not liking to retain these views of the pure and holy God, they chose to think of him as being like some of his works and began to worship such imaginary gods; or they put in his place some lower beings or powers as objects of worship. Hence the terrible judgments which the children of Israel had seen falling upon Egypt and her idols. “Upon those that love me” is delightfully suggestive of the great truth that the essence of all acceptable worship is love. God looks complacently on his human children when they delight in his glory, love his character, rejoice in his blessedness, and make it the best joy of their souls to please him by doing all his will. Such love legitimately flows out in reverent worship and adoring homage. Over against this the worship of idols in place of God is congenial only to the souls that hate God. This command assumes that those who worship other gods really hate the one Supreme Jehovah. Therefore it is that his jealousy burns against them. They withhold from him the love and the homage of their hearts.
