The bible says that those who die in unbelief will not get to heaven
It does not say a person who does not believe in the correct age of the earth will not get to heaven. Yet people claim that would be heresy
My thoughts as well.......there are many saved people that disagree with the 2nd coming, the 70th week of Daniel, the age of the earth, gap theory or no such thing etc....and ALL with opinions <---heretic means opinionated one.......yet they make heaven by faith.....
