This book focuses on the importance of returning to God. It also highlights the reason God created the human being. God wants mankind to live in harmony. He wants us to build, not destroy, to improve, not corrupt. He wants justice to prevail and discrimination to disappear. He wants humans to come together, befriend each other, and not distance themselves and alienate each other. He wants us to be merciful and compassionate, not cruel and apathetic. He wants peace, happiness, and prosperity to rise above misery, hunger, and oppression. He wants us to love one another and live in harmony and good will.

What is happening in the world today is not a state of harmony and good will. It is a world full of greed, wars, oppression, and injustice. In this book, the writer is talking about two of the greatest men of God's creation, Jesus and Mohammad (peace be upon them). He outlines the contributions of both prophets to humanity. Through a well-supported survey of their characters, teachings, and contributions to humanity, he reminds us of what harmony should be like.

The writer breaks down living in harmony into smaller elements such as love, justice, mercy, and compassion. Using situations from the lives of both Jesus and Mohammad (peace be upon them) as role models of behavior, he shows how the two prophets behaved to uphold those elements and teach us how to behave so that peace, harmony, and goodwill shall prevail in the world.

After highlighting that all the messages sent by God have the same basic objectives, he goes on to correct some misconceptions about Islam. He shows the thin line between such concepts as freedom and chaos, firmness and tyranny, advice and slander, fanaticism and forbearance, and others. In this section of the book, he uses examples, quotations, and situations where both Jesus and Mohammad have behaved with the same discretion.

Furthermore, the writer gives a simple but true picture about what Islam is truly like, ending with a section about Jesus in the Quran.
