The statement: "We've heard for days now that Mother Teresa was saved by her good works and her charity " is false.
In her case its not a question Ill concern myself with over much, just that it would be sad if true.
And, again, sadder if the statement is knowingly false.
Her faith or lack of it, true or false, right or wrong is of no importance to me even if it is to others. If you think she had vast faith, fine, if you think otherwise, fine. The state of her faith is not my concern. period.
Do you believe the writer of Hebrews or not?
"But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him." -- Hebrews 11:6
