While much of the bible is, in fact, literary. I tend to believe the gospel writers were both reporting fact and telling a story. While it's not my intention to somehow "prove" the historical accuracy of the gospel stories, because I don't think that's their point. The point of the gospels is to bear witness to what God has done in their lives. And we can go back and forth, arguing over the evidence, offering solid proof for the resurrection's truthyness. But Luke doesn't do that. Luke just proclaims what has been reported to him. And he was probably convinced of the resurrection, not through rational argument, but through the changed behaviour of the disciples. Their lives bore witness to what they had seen. They had gone from grief to joy, from a crowd of scattered cowards to a courageous community. For among them, Christ has risen indeed.
We hear that Easter is NOT just about a dead man opening his eyes. Easter is NOT just about our sins being forgiven. Easter is NOT just about the miracle of victory in the midst of defeat.
Easter is about...(whole thing here)
