The search for wisdom is a great challenge, to act on wisdom is an even greater challenge. There are many questions now and there will be many more questions ahead. There are many internal and external pressures against accepting and acting on truth and there will be even greater pressures in the future.
So yes, it is challenging just like running the Boston marathon is challenging or trying to climb Mt. Everest is challenging. But unlike such "sporting" "part-time" challenges the search for perfect wisdom and the attempt to live by such wisdom is an ongoing eternal challenge and it is real. Thus, only the most courageous people will accept this challenge.
