Jews, Israelite’s, cults, sects, continue to stumble over self-righteousness thinking “repentance” is sufficient for salvation from death in Hell. They are eternally in error.
You can keep the Torah, a religion, to the very best of your ability and you can repent of sin relentlessly, continuously, with sincerity, but if your sin does not receive the blood atonement (Leviticus 17:11) provided only by Jesus Christ by faith, trust, belief, that Jesus is Lord who died for you (Romans 10:9-10), you will perish in your sin and you will perish in the “second death” in Perdition (John 8:24; Rev 20:11-15). You MUST be Born Again by faith in Jesus and receive the indwelling Holy Spirit as Guarantor of that covenant relationship (John 3; Ephesians 1:13-14) to be integrated into the New Covenant and receive the benefits thereof i.e. forgiveness of sin – eternal life – the indwelling Holy Spirit – peace with God, forever (Matthew 26:28; Hebrews 8:12; Romans 5:1).
