2 and that we may be delivered from unreasonable and evil men; for not all have faith. WEB
“that we may be delivered” Refers to being rescued and saved from a dangerous situation. Either physical or spiritual.
“unreasonable and evil men” This phrase means that people with bad intentions who do not care for the truth will never be reached by reasoning with them through the gospel.
“for not all have faith” Either this refers to false Christians that do not have true faith or unsaved people who have decided not to believe in Jesus because they cannot obtain faith through the hardening of their hearts.
