What does the Bible teach about eternal life through Christ?

Eternal life is a significant theme in Christian doctrine, emphasizing a personal relationship with Jesus as the source of life. In John 3:16, it's stated that 'whosoever believes in Him should not perish, but have everlasting life.' This assurance of eternal life reflects the promise of being in fellowship with Christ forever. Those who trust in His name and His saving work are guaranteed a future with Him, demonstrating that salvation is not just a moment, but an eternal relationship that believers will enjoy in glory.
