what is the sin that leads to death

The "sin that leads to death" is a phrase mentioned in 1 John 5:16-17, and it has been a topic of much discussion and debate among biblical scholars. While there are different interpretations, most agree that this sin refers to a deliberate, self-willed, and conscious decision to reject God and His ways, leading to a state of sin that cannot be repented of. Some scholars suggest that this sin is the blasphemy of the Holy Spirit, which involves a deliberate and persistent rejection of Jesus Christ. It is important to note that this sin is different from other sins that can be repented of and forgiven. John advises us not to pray for those who commit this sin, but to pray for those who commit sins that do not lead to death.
