When people ESCAPE from the wickedness of the world by "knowing" our Lord and Savior Jesus Christ (Salvation) and THEN get tangled up and enslaved by sin again, THEY are worse off than before. (What is worse than not being saved?)

Because of THEM, Christ and His true Way will be slandered (2 Peter 2:20,21,2)

For it is impossible to.... "bring back" to repentance-- THOSE "who were once enlightened"—THOSE "who have experienced" the good things of heaven and SHARED in the Holy Spirit, THOSE "who have TASTED the goodness of the Word of God and... the power of (a resurrected life) the age to come"— and THOSE who... "THEN turn away from God." (from Salvation) It is impossible to bring such people back to repentance; by rejecting the Son of God (they once knew) THEY themselves are nailing Him to the cross ONCE AGAIN and... "holding Him up to public shame". (Hebrews 6:4-6)
