First of all the title of this topic assumes that everyone has turned their back to the Messiah which is not true for a lot of people on this forum. It actually is the same as calling people ANTI-CHRIST (like the JW's do in their speeches these days)... Not believing the JW doctrine does not necessarily mean you turned your back to faith.
On the other hand: As I have said in some threads I personally have an open mind now... which in essense means that I am becoming sceptical to scriptures that were written around 2000 years ago and are full of contradicitions. It does NOT mean I am not openminded for a messiah or a God... I can only refer to what I have learned and I have seen a lot of things that were false.
I am not saying God doesn't exist... I am also not saying I do not want to obey God... But what I AM saying is that I want to have faith in someone who also communicates with me personally. Communication is a two-way thing. Communication is also personal which means that if a letter was not written to ME personally I can never ever say that the things that were in it were meant for me. So how on earth can I believe someone who I have NEVER seen or who never showed people in our time that he is alive? In other words: how can I turn my back to someone who I am not totally sure of he excists or excisted? I can only turn my back to someone who is there.
If God (or Jesus) would show me he exists and tells what he expects from me then I will absolutely obey him directly! HE knows I would!
