What does the Bible say about the assurance of eternal life?

In 1 John 5:13, John writes, 'These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life.' This indicates that assurance of eternal life is not only a hope but a present certainty for true believers. Understanding and recognizing one's position in Christ is essential for a full assurance of salvation. Eternal life begins when one is quickened by the Spirit and brought into a relationship with God through faith in Jesus Christ, emphasizing that salvation is a gift from God.
