Martin - sorry to be so long answering! You said "I think Jesus' remarks are intended to make people think about the actions of the heart, and I agree that Jesus is contradicting the law - which is interesting because, if he made those remarks, then he did so before he was crucified, that is, before he had made any once for all sacrifice which, so say, removed the obligation to follow the law."
I did not actually say that Jesus was contradicting the Law. What I was saying was that the vision Paul had was God contradicting it's interpretation - or possibly better to say updating it.
Jesus often went against the Pharisaic interpretation of the law which is what he was doing here. That is different from countermanding the laws themselves.
Tabba, you ask "Why does a person have faith in something for which they have no evidence is in existence?"
It is very difficult to explain to someone who has not had the experience, but I have, on several occasions, had experiences which can not be rationally explained, (or for which the likelihood is so extremely small as to be negligible). The only explanation I can give which satisfies my scientifically trained mind is that something outside our understanding of nature was behind those experiences. That something I call God.
Similarly, this universe is the result of the 'big bang' - or so we are told! (and the explanation does make sense...) OK - but where did the matter which was needed and the required pressure and heat come from in the first place. You can't get ought from nought - as my Physics teacher used to say. People refer to 'the laws of nature' being all that is required for the world to happen and for humanity to evolve on it once the big bang had happened - but how were those 'laws' set? It is my belief that there is something outside the 'natural system' as we know it which brought it into being. That something is (again) what I call God. Our (not just yours and mine, but mine and anyone else's) concepts of what that 'God' is may well be different, but i really do think that there has to have been a 'prime mover' which was not part of the system that is the universe.
An example of science not having an answer *YET* could be dousing (or 'divining' - for water or many other things. I accept that, eventually, an answer might be found to this problem, but I defy anyone ever to answer the question of where the matter making up the universe came from in the first place!

"Life exists, and can be proven to exist" - Tell that to an existentialist! he will reply that only HIS life can be proven to exist - everything else could be a product of his imagination...

"Can you explain why so many people from other religions claim that their god healed them, when they clearly do not believe in or pray to the christian god?"
They are the same God - just different concepts of what that God actually is - God must be beyond our understanding (by definition, since, assuming there is a God, it is God that created the universe and therefore us) so it is not unreasonable for one group's beliefs of what that God is, to be different from another group's.
