Have Separated You

Leviticus 20:7-8 ESV

7 Consecrate yourselves, therefore, and be holy, for I am the Lord your God.

8 Keep my statutes and do them; I am the Lord who sanctifies you.

Leviticus 20:26

26 You shall be holy to me, for I the Lord am holy and have separated you from the peoples, that you should be mine.

We are holy by observing His word and doing it. We are to be holy for He is holy. If we do not, we take His name in vain. 

We are His, not in name only, but through and for His name. 

Otherwise we run the risk of showing up for the wedding feast, but He doesn't know our name, for it is not written in the book of life.
