Hebrews 12:14-16

Warning and Encouragement 14Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord. 15See to it that no one falls short of the grace of God and that no bitter root grows up to cause trouble and defile many. 16See that no one is sexually immoral, or is godless like Esau, who for a single meal sold his inheritance rights as the oldest son.
