Yes... but the thread is about what you
believe...and hopefully if one answers the questions truthfully, or finds answers he hadn't realized before, he can then change directions for a more satisfying result and journey.
Knowing and believing, while both good, are different... believing is more about trust... what are you trusting and why and what do you expect from it, are you getting anything from that trusting... etc. I can KNOW that a tightrope walker can carry me across a chasm in a chair...but until I believe it and trust him to do so, it means nothing.
