It sounds like you're being really positive so that's good.
I'm a little confused about the bible reading. If she is there I'm not sure how she will get the rest by taking them later unless your talking a several hours later. If that is what you mean then she might see that as eating in to her time with the kids.
Anyway as long as the offer is genuine and don't mind her decision (no expectations) then its fine.
The one caution im picking up is that it still feels a little like you're trying to 'rescue' her. Its all a fuzzy area for me so I may be misreading but its something to think about
Have a good day
