Before asking yourself the question: Do I need the Messiah, first ask yourself the question Do I need God? Do I need to study the Bible? President Trump is pictured carrying a Bible.
There are atheists in the world who refuse to believe in God. They may have suffered in the holocaust or have witnessed great tragedies in life which have made them atheists. Atheists live their whole life without faith in God performing their duties to humanity as doctors, lawyers, engineers, teachers etc. Most atheists did believe in God once but lost it. Their faith is compared to a lost object which has disappeared and the hope of finding it has been given up. Every day they witness another tragedy reinforcing their atheism.
