What does the Bible say about the consequences of unbelief?

The Scriptures clearly illustrate that the wages of sin is death, as stated in Romans 6:23. This speaks to the eternal consequences awaiting those who die in their sins without Christ. Unbelief is not merely a lack of faith; it is an outright rejection of God and His truth. The Gospel of John highlights that even after witnessing His miracles, many chose not to believe in Christ, culminating in a warning that those who do not believe have no one to blame but themselves for their eternal judgment. The Scriptures emphasize that if one dies without Christ, they will face God's wrath for eternity.
