“God who sanctifies.” God also requires His servants to be clean vessels

Sanctify yourselves therefore, and be ye holy: for I am the Lord your God.

I AM THE LORD YOUR GOD: Therefore be holy, that you may resemble Him whose people you are, and may be pleasing to Him. Holiness becomes His house and household.

And ye shall keep my statutes, and do them: I am the Lord which sanctify you. Leviticus 20:7-8
