This thread reminds me of when I worked at the mental health institute. There was one patient that thought he was God and there was another patient that thought he was Jesus, and they would constantly say to each other: "you're not my son and the other would say you're not my dad"...if you testify of your self your witness is not true. Jesus himself said this.
John 5:31:
If I bear witness of myself, my witness is not true.

so sorry self proclaimers your witness is not true
