Jesus is indeed our advocate...and mediator {1 tim 2:5} and intercessor {heb 4:14}...yet so is the holy spirit {john 14}...and the holy spirit is our intercessor {Rom 8:27}...Jesus in John 14 clearly says “another” advocate...how long have you had issues understanding the word “another”???
Oh? And you have to add to scripture?
1Ti 2:5For there is one God and one Mediator between God and men, the Man Christ Jesus,
Now your theology throws someone else in there...kind of like Marianism...
Who to believe?
