Christianity never says a person is a born christian. Unless and untill they repent for their sins(which most will never understand) and accept christ as their savior, they are not considered as christians.
That also is not easy and does not make him a permanent christian. A person has to keep himself away from sin his entire life too.
This is the spiritual part of christianity. Only a person who truely understands the truth and purity is a christian.
And for all the immature, impatient people... they need to learn more. Wisdom and knowledge gives you patience.
A impatient person has a blunt mind. And cannot counter a reply in the same level of wisdom.
