The book of Leviticus is the third book of the bible its one of the 5 books known as the of law. This book’s main theme is about holiness, these people were known as Gods Holy people. Their sacrifices were to be animals of spotless without blemish, at the time sin was removed by the blood of animals, but today it couldn’t remove sin.
By death of Christ, that is was meant for us today, to wash away our sins the sins of the world. Jesus died for our sins.
