The good news of Messiah’s resurrection changed the world (Ac 17:6), shattering the worldview of thousands overnight. There’s been nothing else like it, either before or since.
The Resurrection points us to an awesome mystery: Messiah Yeshua dealt with human sin, bearing all the sins of all believers (1Pe_2:24), paying their sin debt in full (Is 53:11) and securing their eternal salvation. But He also offers salvation to all (1Jn 2:2), calling all people to believe on Him, to enter into His rest and be saved. (Ac 17:30). It’s a mystery (Ep 6:19) how He effectually and infallibly saves only a few by dying for them, while also being the Savior of all, even those who ultimately perish. (1Ti_4:10)
I believe the answer lies in God’s infinitude: He’s outside time and space (2Pe 3:8), ever present in every moment of time. Whatever God does He’s eternally doing — He only died once (He 10:10) but He can die for anyone at any time, because He’s still there — dying on that cross. He’s always been there, and He always will be.
The atonement of Christ is limited to believers, but He’s offering it to all; He will save everyone who seeks Him (He 11:6) and make them a new creature. On this day of Firstfruits, where we celebrate His resurrection (1Co 15:23), let’s enjoy the mystery, and glory in our God! (1Co 1:31) He sure is amazing!
