A ger has always been a ger

Hi,

"Why do we say, 'A ger who converts is like a child who has just been born,' rather than say, 'A non-Jew who converts is like a child who has just been born?'

"This is because the souls of future converts were presents at Sinai when we received the Torah; it's only that he waited until now to join."

(Chida, Midbar Kedemot 3:3, based on Shabbat 146a)

Have a great day,
Mordechai
