“Strive for peace with everyone, and for the holiness without which no one will see the Lord.”‭‭ Hebrews‬ ‭12:14‬ ‭ESV‬‬

Peace? How? God’s holiness.

“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;”‭‭ Hebrews‬ ‭12:15‬ ‭ESV‬‬

No bitterness. Bitterness and peace are opposing forces.
