A spiritually lost and deceived Jew mocks Jesus as Messiah: “What is the added value of believing in Jesus as a way to ‘life’ if this way already existed?”

Christian response,

There is no life without Jesus as your Lord. The Torah does NOT provide life nor atonement but only condemnation through a Law that defines sin and condemns the soul to Hell (Romans 3:20; Galatians 2:16) as the Law mandates perfection (James 2:10) and you’re a sinner by nature (Romans 3:23) and you’ve already violated the Law and you are under its condemnation and curse (Galatians 3:10). It is Jesus, alone, that is worthy to make atonement for sin as Jesus entered the World through the hypostatic union fully God and fully man (Philippians 2:8) and circumvented the sin-nature via the seed of the woman (Genesis 3:15), a sin-nature that plagues all of mankind born of the seed of Adam (Romans 5:12); therefore, Jesus, alone, kept the Law in absolute perfection (Matthew 5:17; John 8:46) and walked to the horrors of a Roman Crucifixion and shed His innocent blood as payment for your sin and offers you HIS perfection in place of your imperfection IF you will trust-believe in Jesus as your Lord and Mediator for sin (John 3:16-18; 2 Corinthians 5:21); otherwise, you will die in your sin and you will not be named among the Jewish remnant nor will you enter the Kingdom of God (John 8:24; Isaiah 10:22; Romans 9:27).
