I'm an Aussie too and I describe Christians as being 'born again. Only because you can get a self-proclaimed Christian...and one who is God proclaimed Christian....self-proclaimed Christians are the ones who say that they were baptised when they were kids...grew up in church....believe in A God (it's debatable if they believe in THE God) so that makes them a Chrisitan...in their eyes only.
A born again Christian is one who is actually a child of God...been born of water and of the spirit...and who are now new creations in Christ.
Also, would you kindly not speak about me like I'm some sort of 'concept' or 'version' please...that's so disrespectful!
