We don’t know what’s in her heart because only God can see what is in people’s hearts, why they do what they do, and what makes someone tick. And because we can’t see into anyone’s heart, it’s wrong for us to judge them. We can disagree with their actions (as some have done on this thread in a non-condemnatory way), but condemning them as a person (which many have done on this thread) is a non-starter. It’s not a cop out; it’s really fairly simple to understand, if you have any desire to understand it.
The Lord sayeth "Ye shall know them by the fruits of their labor."
