The Hebrew writer, exhorting brethren to be faithful, tells them Esau was a "profane person ... who for one morsel of meat sold his birthright. For ye know how that afterward, when he would have inherited the blessing, he was rejected for he found no place of repentance, though he sought it carefully with tears" (Heb. 12:16-17).

to themselves the Son of God  afresh") that there is no further incentive to repentance — no legitimate appeal can move them. Or, rejecting Christ's self-sacrifice "there remaineth no more sacrifice for sins" to which they can turn (10: 26-31). These are extreme warnings!!

Besides, Esau seemed only sorry he had lost the blessings, not sorry he had been a "profane person." Isaac "trembled very exceedingly" when he learned he had blessed other than Esau, but said, "yea, and he shall be blessed" (Gen. 27:30-38). When Esau heard this (note, rt) he cried, saying "Bless me, even me also." Again, "Bless me, even me also, O my father and Esau lifted up his voice, and wept" (v.38). The weeping was not in penance, but for the blessing.

While there is life, and while the gospel can still prick the heart, a moral change and eternal destiny may be effected. But this — life consequences may be unalterable, by our having passed the point of no return.
