Leviticus 18:2-3 (NASB)“Speak to the sons of Israel and say to them, ‘I am the LORD your God. You shall not do what is done in the land of Egypt where you lived, nor are you to do what is done in the land of Canaan where I am bringing you; you shall not walk in their statutes.Luke 1:74-75 (NASB)To grant us that we, being rescued from the hand of our enemies,Might serve Him without fear,In holiness and righteousness before Him all our days.1 Peter 1:14-16 (NASB)As obedient children, do not be conformed to the former lusts which were yours in your ignorance, but like the Holy One who called you, be holy yourselves also in all your behavior; because it is written, “YOU SHALL BE HOLY, FOR I AM HOLY.”
Christians are to be holy because our Lord is holy; therefore, he has called believers to walk in holiness while on the earth.
