Do anyone else believe that thoughts are powerless ?

The start of a thousand mile journey begins with the thought and the thought moves the feet and guides one to the end of that journey.

“the good person out of the good treasure of his heart produces good, and the evil person out of his evil treasure produces evil….” (Luke 6:45). 

"Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death" (James 1:15).

Thoughts are powerless on their own, confined to a single brain. Once they are released into words or deeds then they have power. If many people have the same thoughts then mountains can be moved, these multiple same thoughts may have originally come from one influential mind.

Source the bible. Your sinful desires will come to pass and you will do them. Why because you had the sinful desire. I could show you scriptures of this in the bible.

Atheists believe that thoughts are just electrical impulses between molecules.
