What does the Bible say about eternal life in Christ Jesus?

The promise of life in Christ Jesus is a central theme in Scripture. The Apostle Paul emphasizes this in 2 Timothy 1:1, describing himself as an apostle by God's will, proclaiming the promise of life inherent in the gospel. This message is the 'good news' that brings joy to believers, assuring them of eternal life. John 3:16 affirms that whoever believes in Him shall not perish but have everlasting life, emphasizing that this promise is rooted in faith in Jesus Christ. Thus, the gospel is fundamentally the promise of eternal life offered freely in Christ, bringing hope and joy to all who believe.
