Why is belief in God's record important?

Believing in God's record is vitally important because, according to 1 John 5:10, those who do not believe make God a liar. This assertion underscores the gravity of faith; it is not a mere intellectual agreement but a heartfelt conviction that determines one's standing before God. The record of God's Son establishes the foundations of faith that ensure believers understand their relationship with God—leading to life and salvation. Rejecting this record places one in a position of serious rebellion against the truth of God's word.
