Are you Jewish? That’s actually more of the Jewish stance.Again. Sin is disobedience to the Law. The only way to be forgiven for sin is by repenting by complying with the Law, the only way to eternal life.
No one is righteous who does not do what is right.
You have set aside the law entirely and teach others to do the same which amounts to murder.
You are a very naughty boy. Even if you ate every consecrated matzo in the world, celebrated the death of Jesus and drank a vat of communion wine every single day your sins will remain unforgiven.
In a nutshell, it matters more what you DO (obey commandments) than what you believe (Jesus was the son of G-d). Christianity basically exchanged adherence to the law for belief in Jesus.
