The story of the birthright shows us what kind of a man Esau was: hasty, careless, fond of the good things of this life. He had no reason to complain if he lost his birthright. He did not care for it, and so he had thrown it away. The day came when he wanted his birthright, and could not have it, and found no place for repentance that is, no chance of undoing what he had done though he sought it carefully with tears. He had sown, and he must reap. He had made his bed, and he must lie on it. And so must Jacob in his turn.
I. It is natural to pity Esau, but we have no right to do more; we have no right to fancy for a moment that God was arbitrary or hard upon him. Esau is not the sort of man to be the father of a great nation, or of anything else great. Greedy, passionate, reckless people like him, without due feeling of religion or the unseen world, are not the men to govern the world or help it forward. It is men like Jacob whom God chooses men who can look forward and live by faith, and form plans for the future, and carry them out against disappointment and difficulty till they succeed.
II. God rewarded Jacob's faith by giving him more light; by not leaving him to himself and his own darkness and meanness, but opening his eyes to understand the wondrous things of God's law, and showing him how God's law is everlasting, righteous, not to be escaped by any man; how every action brings forth its appointed fruit; how those who sow the wind will reap the whirlwind.
III. It is the steady, prudent, God-fearing ones, who will prosper on the earth, and not poor, wild, hot-headed Esau. But those who give way to meanness, covetousness, falsehood, as Jacob did, will repent it; the Lord will enter into judgment with them quickly. There is not one law for the believer and another for the unbeliever; but whatsoever a man sows, that shall he reap, and receive the due reward of the deeds done in the body, whether they be good or evil.
