The holiness of God is immeasurable. He is pure, righteous, perfect, and desires to have a relationship with mankind, created in His image. While in the Garden of Eden, Adam and Eve were able to live in true freedom and sweet relationship with God. In Genesis 3, sin separated them, and the punishment for sin was imputed. Because of the darkness and depravity of sin, a sacrifice of blood was then required for cleansing and atonement.
