Hebrews 12:15-17

¹⁵ Make sure that no one misses out on God’s grace. Make sure that no root of bitterness grows up that might cause trouble and pollute many people. ¹⁶ Make sure that no one becomes sexually immoral or ungodly like Esau. He sold his inheritance as the oldest son for one meal. ¹⁷ You know that afterward, when he wanted to inherit the blessing, he was rejected because he couldn’t find a way to change his heart and life, though he looked for it with tears.
