Someone said: “The prayers of a man who rejects the Torah is like water off a duck’s back.” Is this true or a Jewish myth?

Christian response,

The Torah can do nothing for you as the Torah only defines sin void atonement (Romans 3:20). If the Covenant of Law had been without fault there would have been no need for the establishment of a New Covenant (Hebrews 8:7).It is only by faith in Jesus Christ as your Lord and Messiah and believing that Jesus died to pay your sin-debt that will you find a Covenant Relationship with the Father (Romans 10:9-10) and that relationship sealed and Guaranteed by the indwelling Holy Spirit (Ephesians 1:13-14)…it is then, and only then, that God the Father will entertain your prayers unless that prayer is one seeking righteousness with Him by faith in the Son, Jesus as your Lord.

The Holy Spirit tells us that God does not hear sinners except a prayer of repentance seeking redemption but if anyone does His will He hears Him (John 9:31) and the Father’s will is this…that you believe in the One He has sent into the World to redeem you from your sin (John 6:29).
