Should a Christian Join the Army?

I pray that this book will not only help Christians choose to be holy for Jesus Christ; but at the same time, I pray that this book helps bring every people around the world to Jesus Christ as well. People will be attracted to Jesus Christ through His teachings in this book. I pray that the Muslim and Jewish people read this book as well and see that we are a loving and peaceful religion and that we do not believe in armies and the wars they wage. Thus will more people be attracted to our religion and to Jesus Christ through the verses of the Bible that are in this book. Not only that, I pray this book may help lead future generations of people (Muslim, Christian, Jewish and all other religions and peoples) to peacefully and with love in their hearts lay down their arms against one another and live in peace with all mankind.
