+ positive mitzvah no. 2
Acknowledge the unity of God and have complete faithfulness that He is one, without any partner.
“Hear Israel God is our Lord God is One” Devarim 6:4
This is the essence of our faith.
After first establishing that God exists, it is then necessary to adhere with complete faithfulness that He is entirely one, with complete unity.
He has no body or physical form and no physical concept can apply to Him.
He is not affected by anything physical and there is nothing secondary to Him.
Besides Him there is no God.
We are all obligated to have this faithfulness at all times and constantly, men and women.
