How do I make something respond to one word in a sentence?

I am using Node JS and Discord JS. I am trying to make a bot respond to a word within any sentence but I can only make it respond to the word in a stand alone sentence. Can anyone tell me what I am doing wrong?Pastebin: http://ift.tt/2BVwVOZ
