It is worth noting that *the writer of the story included consent.* Many other "divine conception" stories that circulating at the time (e.g. Persephone, Leta and the Swan) didn't. This was an important choice *for the writer of the story to make.* *In context,* that's almost a feminist statement.
I would like to point out that “consent” needs to be put in context. If your supreme being ask you for something, are you really going to say no? In that culture, god asked Abraham to kill his son, and the guy just started sharpening his knife.
That's true. But in the context of the times and the surrounding culture, it's a big deal. It makes a difference, even now, when the right to consent to a pregnancy is still an issue.
