It wasn’t the Ressurection that paid for our sins, but His death.
The Cross with Jesus represents The Slaughtered Lamb.
The Victory over sin that He gives us isn’t in His rising, but in His dieing.
Again, what does an empty cross say about the thieves?
It’s not the cross, but The Man on The Cross that makes the difference.
Crosses existed before, after and during Christ, but only “one” had Christ on it is the one that matters.
