Megs,
I don't think that faith negates asking questions, on the contrary, because we have faith in our serach for the truth we know that, when we find the answers, the truth will be there.
People with "weak" faith don't liek questions because not having the answers cause them to question their faith.
How can we know the truth if we can't measure it?
Excellent question, do realize that, truth is subjective to the individual, at least to a certain extent.
The truth is I can run the 100 meters in less than 11 seconds, Bolt can do it in less than 10, far less, his truth is not mine, nor mine his.
Some tend to believe that truth is absolute and perhaps in regards to somethings it is, but in regards to spiritual matters, the truth becomes something very personal and indeed, that is,perhaps, how it shoudl be.
