Leviticus is seen as the third part of the collection of 5 books called The Law. God's holiness is being set apart from evil and He expects His people to be set apart from evil. To be holy is to be set apart to display appropriate behaviour towards God and others. His purpose for His people is to reflect His nature, attitudes and characteristics in their actions. God continually demonstrated His care for the aged, the homeless, the fatherless, the oppressed and the stranger.
Holiness begins in the heart, spreading in the family and community.
Honouring parents, elders and provisions given to the poor is anticipated. The handicapped people are to receive the right treatment, foreigners and strangers are to be treated correctly. Proper sexual relationships are expected, respect towards elders, including not seeking revenge. Believer's become holy before God because of what Jesus Christ has achieved for them. God's Laws are the basis for conduct referring to a personal covenantal relationship, they reveal the level of commitment to God by the quality of behaviour.
