How do we know the resurrection of believers is true?

We know the resurrection of believers is true because it is founded on the resurrection of Jesus Christ, which is central to the Christian faith. In 1 Thessalonians 4:14, Paul states that if we believe Jesus died and rose again, so God will bring with Him those who have died in faith. This assurance builds from the promise that Christ has prepared a place for His followers, securing their future glory. The repeated themes of resurrection and eternal life throughout the New Testament reinforce the certainty that those in Christ will one day rise.
