A non believer is condemned:
John 3:18
Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
If I don't believe I am already condemned, so if being already condemned I cannot be not condemned If I begin to believe right now becasue I am already condemned.
A newborn being a non believer is already condemned, so we are all already condemned.
Touche!
