Is the new birth something where you directly notice that something is different? From one day to the other? I think that for some christians it is like this but for others it might not be so dramatic. What I ask myself how exactly do you know that you really have been born again if you do not see dramatic changes? Some people convert and have a huge salvation experience and automatically change and maybe they are also totally enthusiastic for the first weeks and months and want to tell everybody about Jesus but others don't have such a dramatic experience. I mean how do you know why you are trying to improve and to do all those things which a christian usually does? Everybody has some opinions about what a christian does. A christian doesn't steal, he loves people, he does good things and so on... Now how do you know why you are doing things different after your conversion? What if you are simply trying to achieve these things in your own strength and only follow the commandments because you know that a christian is supposed to do this? Religious people which are not born again but they also try to follow the commandments. When you see a born again christian and a religious person which both read the bible and try to act upon it then how exactly can you tell who's born again and who isn't? And how do you know wether you are really born again or wether you are not simply doing things automatically? The jews for example did all their stuff out of a routine. The ark of the covenant was gone but this didn't disturb them at all, they still held their church services. How do you know wether you are not also doing things out of a routine? After my conversion I knew that many things which I did were wrong and tried to change them but actually I also knew that they were wrong before my conversion. If you already knew it before and then try to stop these things then how do you know wether you're not doing it automatically and it's not God who does these changes in you? What's simply stupid is when everything is so vague and you can either simply accept that you have been born again but you can as well ask yourself if it really worked because you did not have such a dramatic conversion.
