John is addressing a mixed group there....not all believers as you have said in the past.
So are you saying that these words are addressed to unbelievers:
"If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness" (1 Jn.1:9).
You would never tell an unbeliever that if they will just confess their sins then those sins will be forgiven.
In order for an unbeliever to have his sins forgiven he must believe:
"To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins" (Acts 10:43).
If an unbeliever confesses his sins those sins will not be forgiven.
So, again, the words at 1 John 1:9 are addressed to those who are already saved.
Please don't feel pressured to answer what I said.
