You think it's true? What makes you think that?
Jesus' purpose for dying was to take our sin upon Himself so that we would be saved. God's wrath was NOT upon Jesus while He was upon the cross. Neither was God's wrath upon US for being sinners.
Well, God's wrath is poured out on sinners after they die in the lake of fire, right? If Jesus was our substitute would that mean He took the wrath of God for us, because God pours out His wrath on sinners in the lake of fire (and God's wrath might be on sinners before that - to a lesser extent I guess)?
