Let me clarify, you hadn't posted your personal testimony on this particular post. And anyone can give a personal testimony, but I also find that how a person acts and treats others is also part of their personal testimony as well.
You have mocked others Christianity. And have set yourself up as the "all knowing" on matters of others' personal faith.
I have had this debate with you before. You can't possibly know who has called on the Name of the Lord.
I agree with you that if a person does not confess that Christ is their Savior they are not a Christian, but your confession is more than just words you may have spoken at one time in the past, it is also how you live day to day.
How you live, how you treat others, is also part of your confession.
I have never, nor will I ever, accuse you of be saved or not, or whether or not you will end up in Heaven or hell, I am not God, there is no way I can no that. You seem to have a habit of condeming others. Maybe you should think about that.
It has always been the case that how we walk and talk our way through everyday life is the genuine (and lasting) testimony to our acceptance of salvation and our committment to daily Christian life. It's the only "witness" that will matter, because it will be the definition of our faith, open for all to see.
Before I became a Catholic, I remember be severely rebuked about something that was relatively benign--this rebuke came to me in the presence of others (Jesus always took people aside---except for the Pharisees, of course) and was delivered to me by a "Bible-believing" Christian.
Then I remembered the co-worker who quietly supported me in my work and treated me with respect. That person was instrumental in getting me interested in the Catholic Church.
I've heard stories just like mine from many people.
