faith and believing...

faith?? ive been questioning so many things lately...just so unsure...like how do u believe when u have no proof? im not gna directly hint this out coz many ppl may nt like it and may not agree with my opinion...a lecturer of mine pointed this out...she said that students nowadays dont blieve in heaven and earth...we believe in heaven ON earth...how true is this? maybe it is more obvious than it was before...many ppl are raised up and these things are just instilled in them and they hav no opinion or no say abt it watsoever....maybe its better if u believe on ur own...but what do u do if its already like that? this really confuses me...been thinking abt it way too much...if u hav any opinions on faith and beliefs...leave a comment...=)
