I think the important thing to recognize about a messenger like Steve Quail is to distinguish to whom God has sent him with his specific message. I do not think he was sent to us who are watching and are ready to be raptured and therefore his message is as if there was no rapture for indeed for those to whom he was sent with his message of warning, there is no rapture for they are not ready but this does not mean that there is no rapture at all. And any of those who will hear him and repent can still get in and be included in our rapture until it comes and the door is shut. Many have been lulled into a false sense of security and will be unpleasently surprised when they find that their escape did not occur and as Quail said, many will become angry and renounce Christ and turn on Christians because they have always looked at it as 'what's in it for me?' anyway (although many of them will repent and be still saved during the tribulation but have to die).
 
So do not be troubled by Quail's saying that there is no pre trib rapture or that the preaching of it was some trick to ensnare people into a false hope. This does not have anything to do with our blessed hope except to say that we are to not let it steal our hope or crown because we the bride who love His appearing are still escaping first.
 
I think of Steve Quail like Apostle Paul was to the Jew, as "one born out of due time" or premature. Because Paul was like a Jew at the end of time who will look on Him whom they pierced and finally receive Him but Paul came early because God selected him to be His messenger. Likewise, God selected Steve Quail who admits to having been very carnal up until God grabbed him and made him His messenger to other carnal ones so that they might hear the message of warning. His message is for those who need it but don't let it steal your crown if you are not one to whom he was sent. Rather let it encourage us because the time is at hand for our deliverance.
