Seven Verses for Atheist Thoughts

Read the following carefully, and let me know your thoughts:

"Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. But whosoever shall deny me before men, him will I also deny before my Father which is in heaven. Think not that I am come to send peace on earth: I came not to send peace, but a sword. For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. And a man's foes shall be they of his own household. He that loves father or mother more than me is not worthy of me: and he that loves son or daughter more than me is not worthy of me. And he that takes not his cross, and follows after me, is not worthy of me. He that finds his life shall lose it: and he that loses his life for my sake shall find it." (Matthew 10:32-39)

Are His words the ravings of a madman, or is this God in human form? If you don’t believe that Jesus said these things, who did? What did He mean regarding the sword? What is the meaning of the last verse?
