Are We Giving Enough Information?

I like to get to the root of things. That way you can really resolve the issue instead of simply putting bandaids on it. For the past few years I've noticed that the Young Calvinists are having conniptions about who is and who isn't born again in evangelical churches. But I think they have at least one good point and that is - how much gospel do you have to hear to become a Christian. And that leads to the second question - are people hearing enough today to become Christians? I'm not talking about "Jesus Followers" of Rabbi Jesus. I am talking about people getting converted through Jesus Saviour. So, what do you think? How much gospel do we need to hear? I am not asking HOW we should present it (that will be another post), only IF we are giving enough information.
