You can see how detailed the Law of Moses was and how difficult for the people to follow.
There were other Laws on what to do if your farm animal harms your neighbor or you accidentally knocked out the tooth of a slave; and there were many different Laws about sexual behavior.
Each Law contained either a sacrifice to be given for forgiveness or it contains a penalty, including death.
There were Festivals to keep, many you may recognize by name like Passover or Pentecost. There were seven of these that were observed throughout the year.
Sacrifice of animals was very common. To be a priest meant you were going to spend a good portion of you time killing, burning the carcass, or cleaning up afterwards. It was not a pleasant duty if you can imagine.
Though God required these sacrifices, it is written in Hebrews that the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect. For then would they not have ceased to be offered? For the worshipers, once purified, would have had no more consciousness of sins. But in those sacrifices there is a reminder of sins every year. For it is not possible that the blood of bulls and goats could take away sins. Heb 10:1-4
The Law is a shadow of good things to come. Just like your shadow may look like you, it isn’t you. But if you follow the shadow to the source, you are found!
Follow the Law and the source is Jesus.
This means that Jesus is the fulfillment of the Law. Although the sacrifice of an animal was required under the Law of Moses, it is not possible that the blood of those animals could take away sin.
Through Jesus is a perfect sacrifice for the complete forgiveness of your sin.
While the priest had a daily duty to sacrifice and sacrifice and sacrifice – it was soon apparent that it was always the same people bringing the same sacrifices for the same sins.
And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, from that time waiting till His enemies are made His footstool. For by one offering He has perfected forever those who are being sanctified. Heb 10:11-14
It is Jesus that enables you to be forgiven and have a consciousness of your actions (sin) so as not to do them. In other words, you may still sin as a Christian but it grieves you and you seek God’s forgiveness, grace, and mercy.
Praise Jesus for what He has done!
I encourage you to read the Law of Moses in Exodus, Leviticus, Numbers, and Deuteronomy – although much of it is contain in Leviticus.
