Obedience

Consecrate yourselves, therefore, and be holy, for I am the LORD your God. Keep my statutes and do them; I am the LORD who sanctifies you. -Lev 20:7-8

God gives us two reasons to obey him:

1. Obey him because he is the LORD. Implied here is that he is holy.
2. Obey him because he sanctifies us. He does the work of changing our heart and making us clean, yet/because of this we are to obey him.

Both of these reasons are a response to God's character and work. Neither are a means to earn salvation.
