How do we know eternal life is promised to believers?

Scripture affirms the promise of eternal life through various passages, notably in John 3:14-16 and John 10:27-30. Jesus explicitly states that those who believe in Him will have eternal life and will never be plucked from His hand. This assurance is rooted in the finished work of Christ, emphasizing that our expectation of eternal life is based on His merits rather than our own. Romans 8:16-17 further confirms our identity as heirs with Christ, solidifying that our hope for eternal life is not in our efforts, but in the promise of God’s word.
