Leviticus is largely about directions for sacrificial ceremonies and worship, and might seem hard for the modern reader to relate to. However, the New Testament reveals the great extent to which the entire Tabernacle enterprise symbolizes eternal truths that are as relevant to the New Testament believer as to the Old.
In particular, the New Testament book of Hebrews says that all the Tabernacle items are copies of the real thing in heaven. It further discusses the meaning of the priesthood and sacrifices, all of which look forward to Jesus Christ’s ministry on behalf of a fallen race.

God will give very specific instructions that are to aid the Israelites in setting themselves apart from their pagan neighbors who embrace the destructive behaviors that tend to fracture society (Leviticus 18). Ultimately, God is wanting His people to exhibit love to their fellows and even to strangers. The New Testament quotes Leviticus 19:18 many times, “You shall love your neighbor as yourself.” Jesus calls this the second greatest command in the Law (Matthew 22:36-40) with the first being “Hear, O Israel! The LORD is our God, the LORD is one! You shall love the LORD your God with all your heart and with all your soul and with all your might” (Deuteronomy 6:4-5, Mark 12:29).
The Apostle Paul points out numerous times that every command in the Law can be fulfilled (kept) through love. (Galatians 5:13-15, 1 Timothy 1:5, Romans 13:9). When we love someone, we will not be inclined to hurt them, steal from them, envy, hate, or defraud them, but will tend to cherish, admonish, and seek their best, in mercy and truth. This is because love is the bond of perfection (Colossians 3:14).
