It is another area of debate. I am definately on the side that believes that baptism is necesary, simply because it is not possible to look at a conversion in the NT that didn't involve baptism. Based on evidence, it's clear to me that early believers participated in baptism (that is, a full submersion in water as an adult). I have heard some people present evidence that contradicts this, but I have not been convinced that one can accept Christ and be saved without baptism, at least according to the New Testament.

And again, a conversion to me is only the beginning. All of that is a moot point if one does not carefully study the Bible and reflect on the words of Christ. THOSE are the most essential aspects of Christianity. If you don't understand and accept Christ and his teachings, it doesn't make a difference. That's something we could probably all agree on.
