Leviticus is the central book of the Pentateuch, and at its center it teaches us an important lesson - a lesson which motivates us for global missions - the substitutionary atonement of Jesus Christ. Man is not justified by following the law, his uncleanness is too great. But God's unilateral grace toward fallen man makes us holy. As the nation of Israel once gathered at the one place where sacrifices were made, so now the church goes out into all the world, now already made holy by the death and resurrection of Jesus, to be holy as God is holy. Holiness is missiological.
