In 2 Corinthians 5:17, Paul says "Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come" (ESV). Paul understands the incredible reality of being 'made new' in Christ. Before Christ, he was dead in sin, but now he is truly alive in Christ and empowered by the Holy Spirit. The promise of his future heavenly reward caused him to live his earthly life with urgency. Paul's letter is an encouragement to live courageously and joyfully in the midst of opposition, knowing our final destination is not in this world but in the Kingdom of Heaven.
