why?

sometimes i really don't understand why ... why there are so many ppl refuse to accept God? even if they have attended to many church's activities, heard the gospel and testimony many times???

why don't we believe in thing that is so obvious (creation), real (history) and good (gospel)???

i start to feel frustrated and angry about them, i know i should not. but i donno ... maybe we all have our own struggles. and i still believe God has His own timing. :)
