Could it be those who have been told the Gospel before the 7 year trib that are now blinded from the truth now. And People who have not heard are given a chance. You say people that we shared some will come to faith. I think it makes more sense because it says they refused to belive the truth ie those we have shared with and God sends them a powerful delusion so That they belive lie. Give it some thought sometimes we get in a rut because so many believe one way. But to me it makes more sense that it’s those who have not heard come to faith, at least some.
