To Christians, the resurrection means many important things. It means that those of us who are united to Jesus by faith will be resurrected just like He was. It means that God fully accepted the sacrifice for sins that Jesus offered on the cross and that it was infinitely more than sufficient to pay our moral debt. It means that Jesus now lives to lead, rule, protect, intercede for, and do good for His people who are still alive on earth. And it also means that God ratified, endorsed, vindicated, and confirmed all of Jesus's claims about who He was and what kind of authority He possessed.
