Hebrews 6:6 “If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.” Look up Hebrews 6:1-7. Repentance is sincere regret or remorse and is necessary for salvation. A person can not be saved until they realize that they sin and deserve to go to hell. Repentance is turning from death to Christ. Real repentance will bring a change to our lives.
