Hebrews 12:14-17
Do Not Reject God’s Warning
12:14 Pursue peace with everyone, and holiness, for without it no one will see the Lord.
12:15 See to it that no one comes short of the grace of God, that no one be like a bitter root springing up and causing trouble, and through him many become defiled.
12:16 And see to it that no one becomes an immoral or godless person like Esau, who sold his own birthright for a single meal.
12:17 For you know that later when he wanted to inherit the blessing, he was rejected, for he found no opportunity for repentance, although he sought the blessing with tears.
