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

⁷ 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.

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