I wouldn't say it was God's intentions. He mentioned in the previous episode how it was basically Sam's fault that Amara was set free and God had "barely" locked her up, meaning he tried and now she's out.

As for the lack of significance in the previous seasons, I guess you're right. So much has happened that there is no point in thinking about the past, and they can only (or choose to only) focus on the present/season 11.

It can also be considered a continuity error, considering each episode has a different writer.
