What are the consequences of not believing on the Son of God?

The consequences of not believing on the Son of God are severe and dire, as articulated in John 3:36, which states, 'He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.' This portrays the ultimate fate of unbelievers: condemnation and the absence of spiritual life. Additionally, 1 John 5:10 reminds us that failing to believe makes one guilty of calling God a liar, emphasizing the gravity of rejecting the truth of Christ.
