2. Do they depend upon the fortifications of their country, both by nature and art, and glory in the advantages they have thereby? Those also shall deceive them. They dwelt in the clefts of the rock, as an eagle in her nest, and their habitation was high, not only exalted above their neighbours, which was the matter of their pride, but fortified against their enemies, which was the matter of their security, so high as to be out of the reach of danger. Now observe, (1.) What Edom says in the pride of his heart: Who shall bring me down to the ground? He speaks with a confidence of his own strength, and a contempt of God's judgments, as if almighty power itself could not overpower him. As for all his enemies, even God himself, he puffs at them (Ps. x. 5), sets them all at defiance. Their father Esau had sold his birthright, and yet they lifted up themselves, as if to them had still pertained the excellency of dignity and power. Many forfeit their privileges, and yet boast of them. Because Edom is high and lifted up, he imagines none can bring him down. Note, Carnal security is a sin that most easily besets men in the day of their pomp, power, and prosperity, and does, as much as any thing, both ripen men for ruin and aggravate it when it comes. (2.) What God says to this, v. 4. If men will dare to challenge Omnipotence, their challenge shall be taken up: Who shall bring me down? says Edom. "I will," says God. "Though thou exalt thyself as the eagle that soars high and builds high, nay, though thou set thy nest among stars, higher than ever any eagle flew, it is but in thy own imagination, and thence will I bring thee down." This we had Jer. xlix. 15, 16. Note, Sinners will certainly be made ashamed of their pride and security of their pride when it has a fall and of their security when their confidences fail their expectation.
