I recommend and applaud a healthy skepticism, without it you would likely fall prey to snake oil, empty promises and flim-flammery. However, when skepticism is allowed to become a deliberately faithless stance or attitude it prevents all that is new and edifying from coming into your life and blessing it.

For the skeptic in you, consider these: 

"There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance – that principle is contempt prior to investigation." 
Herbert Spencer
(Big Book, Page 184) 

Do not let yourself be tainted with a barren skepticism.
Louis Pasteur

Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or ignorance.
Bertrand Russell

The path of sound credence is through the thick forest of skepticism.
George Jean Nathan

Galileo Galilei's 'telescope' was pronounced a "work of the devil" by 'experts' of the day. He was nearly burned at the stake for daring to claim that the Earth was round, not flat, and that it orbited the Sun, not vice versa. He spent the remainder of his life under house arrest for daring to speak such 'heresy'. The concept of looking through a tube that would make distant objects appear closer was 'witchcraft', while a round earth was 'counter-intuitive', 'illogical', 'impossible'... after all, if the earth were round, we'd all fall off, or fly into space!

Every new idea or invention has its detractors and disbelievers, it happens over and over again, it is the way of progress. So many things you hold in your hands on a regular basis today would have been considered witchcraft in days gone by.
