Hebrews 12:14-17 (ESV)

¹⁴ Strive for peace with everyone, and for the holiness without which no one will see the Lord. ¹⁵ See to it that no one fails to obtain the grace of God; that no “root of bitterness” springs up and causes trouble, and by it many become defiled; ¹⁶ that no one is sexually immoral or unholy like Esau, who sold his birthright for a single meal. ¹⁷ For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears.
