How Cast a ray between two points and return all points intercepted?

Hi I am trying to return all objects in between two points. I think the best would be to use a ray but I think it only returns the first objects. I was wondering if there was some way to do this? Or if there was a better way instead of a ray?

I would need to return all objects between the two points. Attached is a picture trying to explain it a bit better.

I would like to add the selected objects to a list so that I could compare if it were a word in the list. Order is only need from front to back or back to front.

Hopefully this makes since and thanks in advance to any experts willing to help a newb :D.
