Do you know Chip Hardy? Check in with him if you can. We had an extensive conversation on original sin and found my proposal aligns quite closely with his reading of Genesis (repeated exile as God’s merciful response to sin).
@kkeathley brought me out to SEBTS for a private event as a warm up for Dabar. It was extremely helpful. I’m very indebted to him. Have you read this yet: Ken Keathley: Notes from Dabar and a Baptist's Hope?
