The following is an excerpt from
The MacArthur New Testament Commentary on Hebrews 12.
That there be no immoral or godless person like Esau, who sold his own birthright for a single meal. For you know that even afterwards, when he desired to inherit the blessing, he was rejected, for he found no place for repentance, though he sought for it with tears. (12:16–17)
Perhaps the saddest and most godless person in Scripture outside of Judas is Esau. On the surface, their acts against God do not seem as wicked as those of many brutal and heartless pagans. But the Bible strongly condemns them. They had great light. They had every possible opportunity, as much as any person in their times, of knowing and following God. They knew His word, had heard His promises, had seen His miracles, and had had fellowship with His people; yet with determined willfulness they turned their backs on God and the things of God.
Esau not only was immoral, but was godless. He had no ethics or faith, no scruples or reverence. He had no regard for the good, the truthful, the divine. He was totally worldly, totally secular, totally profane. Christians are to be vigilant that no persons such as Esau contaminate Christ’s Body. See to it … that there be no immoral or godless person like Esau.
Jacob, Esau’s brother, was not a model of ethics or integrity, but he genuinely valued the things of God. The birthright was precious to him, though he tried to procure it by devious means. He basically trusted God and relied on God; his brother disregarded God and trusted only in himself.
When Esau finally woke up to some extent and realized what he had forsaken, he made a half-hearted attempt to retrieve it. Just because he sought for it with tears does not indicate sincerity or true remorse. He found no place for repentance. He bitterly regretted, but he did not repent. He selfishly wanted God’s blessings, but he did not want God. He had fully apostatized, and was forever outside the pale of God’s grace. He went on “sinning willfully after receiving the knowledge of the truth,” and there no longer remained any sacrifice to cover his sins (Heb. 10:26).
We must be vigilant so that no one turns from the truth, becomes bitter, or follows the course of selfish Esau, who wanted God’s blessing desperately—but not on God’s terms (cf. Mark 10:17–22).
