Many Christians in the evangelical tradition use words like "conversion," "regeneration," "justification," "born-again," etc. all as more or less synonyms to mean "becoming a Christian from cold." In the classic Reformed tradition, the word "justification" is much more fine-tuned than that and has to do with a verdict which is pronounced, rather than with something happening to you in terms of actually being born again. So that I'm actually much closer to some classic Reformed writing on this than some people perhaps realize.
