Monotheism is the belief in a single God. There are many varieties of monotheistic religions. These include Islam, Judaisms, Zoroastrianism, Hinduism, and Zoroastrianism. Each religion and practice has its own set beliefs. Let's take a look at the differences.
Islam
Islam is a monotheistic religion which emphasizes God's Oneness. Islam teaches that God is the only Creator and the only one deserving of worship. This idea is reinforced throughout the Qur'an. The Oneness of Allah is the focus of most Qur'an verses.
Christianity, Judaism or Islam are the main monotheistic religions. These three traditions trace their origins to Abraham. Abraham, the father of Abrahamic religions was asked to sacrifice his only child, but God intervened and saved him. He then offered Abraham to sacrifice a ram. The Bible identifies the promise messiah as the main focus of Jewish people's faith.

Islam considers worship to be an integral part of Islam. Worship does not just include prayers and rituals. All of us need to engage in worship that pleases God. These activities might include charity donations, seeking out knowledge, or being an agent of good in this world.
Judaism
Judaism can be described as a monotheistic, ethnic religion that belongs to the Abrahamic family. Its roots lie in the Bronze Age of the Middle East. It is based on Jewish beliefs and history. It is one of the most popular religions in the world and has been for more than two thousand years.
Jewish people believe God created all things and that all human beings are made in God's image. Judaism teaches that God will judge us at the end of our lives. It has many holidays, traditions, rules and is distinct from other religions. There are approximately 5 million Jews in America today. There are thousands synagogues scattered throughout the country. Jewish people believe it is important to help others and make the world better.
The Torah portrays polytheism to be a wicked religion. Deuteronomy 2:16-17 describes God's accusation of the Israelites of worshiping false gods. Modern scholarship suggests polytheism has its roots within monotheism, which is a far more complex question than many believe.

Zoroastrianism
Zoroastrianism has a deep impact on the worldviews its followers, even though it is one of most obscure religions. Its teachings include the concept of hell and heaven as well as the Judgment day and free will. It also teaches the existence of angels and demons.
Zoroastrians believe humans can reach perfection in this lifetime and then go on to meditate upon their deeds in a future life. The good balance of deeds leads to paradise, while the evil balance leads to hell. Zoroastrianism encourages individuals to be good and moral beings.
Zoroastrianism can be considered the oldest and most ancient religion in the world. Its adherents were a wealthy minority who believed honesty, respect, education, and justice. They fled India and became the Parsis.
