In that particular case, don't you have pretty good, solid evidence to provide that man that you have the knowledge you claim to have? That is, that you, yourself, are going to the same place he himself is actively trying to go, and that there you are, walking toward the exact gate you told him you both should be walking toward to get the job done. And, being inside an airport, with security and other people all around, the man can be pretty sure you aren't just lying to him to take him somewhere else, because then he'd just appeal to those around him that you were a crazy person who was trying to do something strange with him, and you would likely be tackled by security and led away. The point being - there are all sorts of indicators in real life that this man can key on to know that what you are telling him is the truth. In the case of your religious beliefs, the indicators you have are not nearly as reliable, and in fact, are based on claims made about a reality that no one actually experiences.
Caliber of evidence is extremely important, and all I can see in your claims and presentations of STORIES when asked for clear-cut answers, is that you don't seem to think that it is important. In fact you seem to flout the idea of good evidence every chance you get.
