The spiritual system of God, which was given unto the Jewish nation (Israel) through Moses had special mediums that were messengers who brought God’s messages to the people.

Mediums like; the prophets, and the seers, downloaded God’s information from the spiritual realm and brought it to the people in form of prophetic oral spoken words or commandments of God’s messages. 

Abraham the Son of Terah, Terah being the grand son of Shem, became a prophet of God who obeyed the spiritual instructions of God’s voice. Through Abraham the faith in one God was restored back into the earth after the fload of Noah.
 
The priests, the levites, and the teachers (rabbis) took those prophetic messages and turned them into practical activities, instructions, called mitzvah or mitzvot in Hebrew Torah commandments), which enabled the people to connect to God during the practicing of those commandments.

As the people were learning, practicing, sharing, teaching, speaking God’s word and keep His holy commandments, every physical act of faith that they did, brought the reality of God’s presence and blessings into the congregation (community) of Israel.

Through Abraham, who begot Isaac and Isaac begot Jacob, and Jacob begot the twelve tribes of Israel, there came forth a spiritual concept of believing in one God which was different from the other cultures and traditions that were on the earth.

The spiritual concept of believing in one God gained it’s ultimate authority during the incident when God gave Moses the ten commandments on mount Sinai as it is written in Exodus 19:1-25 & Exodus 20:1-17.

Moses was the man who wrote down the Torah five books of Moses (being Genesis, Exodus, Leviticus, numbers and Deuteronomy).

During the colonization of the world by Europe, many spiritual ideas which derived from spiritualism, including the concept of believing in God began to be erased contradicted, despised and aborted from the minds of the people by the academic structure and teachings of the western culture of Europe.
