The other day Fr KT's sermon was quite revealing... that is only to those who really understood or took pains to see the connection he was subtly making. His main point was that there is a grave danger in giving food to those who are not hungry. To the one who is hungry any food would do. The hungry man is not going to throw a tantrum about the variety of food or anything of that sort. His only and only need is to satisfy his hunger. (Of course, that does not mean you give him thrash.)
On the other hand, giving food to one who is not hungry will incur his wrath and ensure a string of complaints and grumblings. The need is not what you provide but something else. Therefore what you now provide will always have something or the other deficient.
The same applies to human quest for God... and for that matter anything in life. Only those who are tuned in to that direction will progress, others keep wandering and never reach anywhere. (Now that is not a real problem, wandering about, but when they start blaming everyone and everything around them for their present state or keep grumbling, then it surely is something that I personally do not approve of.)
