Dear Preachers of the Truth:
Religion is something into which everyone inquires some time in life. To many the subject becomes so involved that after a while the individual says: "Well, I just can't see why there are so many religions, and I don't know which is true or which is false. I'll just believe there is a God and let it go at that"
But is that enough? No; not if the person wants to live, because only by the continual taking in of knowledge of Jehovah God and of Christ Jesus is everlasting life obtained.
So, then, we as Jehovah's witnesses have a big work to do in straightening out this matter of religion in the minds of the people. The book "What Has Religion Done for Mankind?" takes up the many kinds of religion and discloses to you and the people whom you will have the privilege of instructing the way of true worship and where all the false religions came from and how to help the people to get free from them.
If you can get those seeking the truth to read and study this book, it will mean so much to them, and they will be thoroughly grateful to Jehovah for the understanding of his Word.
Familiarize yourself with the contents of this book and put your acquired knowledge to work in enlightening all those who sit in darkness and the shadow of death.
Yours for the 'clean worship',
