How do we know Jesus' resurrection is essential for salvation?

The resurrection of Jesus is pivotal to Christian faith and salvation. According to Romans 4:25, Christ was raised for our justification; His resurrection ensures that the penalty for our sins has been paid in full and accepted by God. This event not only demonstrates God's power but also guarantees the believer’s own resurrection and eternal life. It validates everything Christ taught and accomplished during His earthly ministry. Without the resurrection, no assurance of salvation could be given, and believers would remain in their sins, as stated in 1 Corinthians 15:17. Thus, the resurrection is a fundamental aspect of the gospel, affirming that through Him, believers are no longer condemned.
