Why is the resurrection of Christ central to salvation?

The resurrection is crucial because it confirms Jesus as the Son of God and the validity of His sacrifice. Romans 1:4 states He was declared the Son of God with power according to the Spirit of holiness by resurrection from the dead. In Acts 13:33, Paul emphasizes that God's promise fulfilled through the resurrection grants assurance of our justification. Because He lives, believers are assured of their own resurrection and eternal life, showing that the resurrection is not merely a historical event but the cornerstone of our hope.
