How do we know that Christ’s resurrection guarantees our own?

The certainty of believers' resurrection is rooted in Christ’s own triumphant resurrection, which is foundational in Reformed theology. As described in 1 Corinthians 15:20-22, Christ's resurrection is termed the 'first fruits,' indicating that His victory over death is a precursor and guarantee of what awaits all who believe in Him. Because He has conquered sin and death, believers can be assured that their resurrection is equally secured through Him. Romans 6:5 reinforces this assurance by stating that if we have been united with Him in a death like His, we shall certainly be united with Him in a resurrection like His. Therefore, Christ’s resurrection is not an isolated event; it is the pivotal moment that ensures and guarantees the future resurrection of all His followers.
