In my opinion, the ability or inability of God to interfere in the lives of humans in such a way, that tragedy can be thwarted, suffering can be alleviated, loss can be reversed, etc ... is to be taken seriously, and treated with respect. The prayers of people in times of trouble, seeking God or "anyone out there" to help them ... is sometimes a last resort, sometimes a first resort, but regardless, they are not often prayers given in jest or flippantly. In such times as hunger, need, pain, fear, etc ... "God please help me" is a common desire, hope, and thought, of the heart and mind and perhaps soul.
Thus, for certain types of individuals to flaunt their authority or the amazing things they believe God has done for them, in front of those who are praying for the same things and still in need, yet, seemingly NOT seeing their prayers answered ... I would think that behavior such as that, would often be cruel and, imo, doing a disservice to God and His choices, Himself.
If a starving person in front of me, is begging God-or-anyone-who-will-listen for food, and I am there, healthy and snacking, claiming how great God is for providing my snack, while he is starving ... and I do nothing to help him, but continue to proclaim the good things done for me ... that seems unloving and cruel. IMO, one reason we do not see "war stories" by the Apostles and others for the sake of simply telling them, is for that very reason: they were serving others, not just themselves.
HOWEVER ... people still enjoy being free to discuss things with their peers. They still desire to speak freely about what is happening to them, good or bad, better or worse ... despite the world around them. People are starving all over the world, yet here we are typing on computers, no doubt having food and clean water within reach. So ... if someone believes God is speaking to them about world wide horrors, that they may can do nothing about ... or God is telling them where their lost car keys are, while people are suffering tragedy at the exact same time ... with whom will they be able to openly share such experiences and explore them ? Would it not be among peers ... those who also believe ?
"God told me" stuff isn't always seeking glory for oneself, simply because the experiences are being told. Context plays a key. Sometimes, I believe it can be cruel and unloving and disrespectful. However, other times, it's also just sharing what is happening in one's life with others who are going through similar things, whether you fully understand it or not. A forum that is full of people claiming to believe in God, many of which claim God still communicates with them and has His hand in the lives of humans today ... seems to be an ideal place for "God told me" types to say what is on their mind and share their experience.
