How do we know that Christ will return?

The certainty of Christ's return is rooted in His resurrection, which serves as the first fruit of the resurrection to come for all believers. In 1 Corinthians 15, Paul emphasizes that 'if Christ be not raised, your faith is vain' (1 Corinthians 15:17), highlighting the necessity of the resurrection as a guarantee of the future resurrection of His people. Additionally, Christ Himself spoke of His return in glory, as he predicts in Matthew 16:27. The consistent witness of Scripture grounds our hope in His return, assuring us of God's sovereign plan.
