Welcome NoMoreJWGuilt. Looking forward to hearing your about your JW experiences.
I'm so glad you asked this question, because it prodded me into looking for proof in the org's literature of how they falsely represent the wording in Hebrews 13:15 - "....public declaration to his name."
Every JW has been led to believe that this verse refers to the name of Jehovah, and yet, I had to go back 46 years to find an org quote which explicitly claimed this -
w73 5/1 p. 260 What Does God’s Name Mean to You? - Does Your Teaching Truly Honor God's Name?....Do you ‘publicly’ declare your faith in God’s name?
If asked, the vast majority/all JW's would answer, 'Jehovah's name' - not 'Jesus.'
