“When you were a kid you were told that you have a mysterious spirit that supposedly floats around wherever you go”
I must have missed that memo.
A fuller explanation of the biblical basis for angels in general and Guardian Angels specifically is found at http://www.whatchristianswanttoknow.com/are-guardian-angels-biblical/ , Are Guardian Angels Biblical?
You’ve missed out on a lot of those memos based on your postings.
But they are still available to you, if you’ll but ask the Lord into your heart. Prayers up.
