Contradiction with Matthew 7:13
Hebrews 12:13 suggests creating a straightforward path for healing, but Matthew 7:13 implies following the challenging narrow path, which might not be straightforward.

Isaiah 59:8: The way of peace they know not; and [there is] no judgment in their goings: they have made them crooked paths: whosoever goeth therein shall not know peace. [judgment: or, right]
Contradiction with Proverbs 3:6
