Hebrews 12:14-17

14Pursue shalom with everyone, and the holiness without which no one will see the Lord.

15See to it that no one falls short of the grace of God; and see to it that no bitter root springs up and causes trouble, and by it many be defiled.

16Also see to it that there is no immoral or godless person—like Esau, who sold his birthright for one meal.

17For you know that later, when he wanted to inherit the blessing, he was rejected. He found no chance for repentance, though he begged for it with tears.
