A. Breaking the 10 commandments (1 John 3:4) B. Failure to believe in Jesus I vote for both A & B, however Ray Comfort appears to be wrong on this one. From the book What did Jesus Do? Jesus in the gospels speaks of the blasphemy of the Holy Spirit being the unforgivable sin, and that s a rejection of Him. He did not mention breaking the 10 commandments, He said rejecting Him as savior is the sin that sends one to Hell. It is not often but this is one point where I disagree with Ray Comfort.
