Strive for peace with everyone, and for that holiness without which no one will see the Lord.  See to it that no one be deprived of the grace of God, that no bitter root spring up and cause trouble, through which many may become defiled, that no one be an immoral or profane person like Esau, who sold his birthright for a single meal.  For you know that later, when he wanted to inherit his father’s blessing, he was rejected because he found no opportunity to change his mind, even though he sought the blessing with tears.
