This sermon is Mel Purvis' exposition on the warning found in Hebrews 12:16–17—the story of Esau, who "for one morsel of meat sold his birthright," and afterward "found no place of repentance, though he sought it carefully with tears." Purvis uses Esau as the supreme biblical picture of someone who:
Traded eternal blessing for temporary gratification
Lost something sacred without realizing the cost
Woke up too late
Tried to repent but could not
Discovered the irreversible consequences of despising the things of God
The sermon is a warning about spiritual carelessness, appetites, carnality, compromise, and the danger of crossing lines that God will not uncross.
