As we have seen, that explanation simply goes like this: we sinned, God sent Jesus to die for us, we are saved. No mention of Israel. But when you leave out Israel, your shortened story will easily tip over into a non-Jewish way of thinking, into, as we have seen, a platonic view of the ultimate goal (“heaven”), a moralistic view of the human vocation (“good behavior”), and a downright pagan view of salvation (an innocent death placating an angry deity).
