“For I am the LORD your God: ye shall therefore sanctify yourselves, and ye shall be holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that creepeth upon the earth. For I am the LORD that bringeth you up out of the land of Egypt, to be your God: ye shall therefore be holy, for I am holy.”
Leviticus 11:44-45 KJV

Isaiah 38:1 KJV
“For in mine holy mountain, in the mountain of the height of Israel, saith the Lord GOD, there shall all the house of Israel, all of them in the land, serve me: there will I accept them, and there will I require your offerings, and the firstfruits of your oblations, with all your holy things.”
Ezekiel 20:40 KJV
“Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts. Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar: and he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.”
Isaiah 6:5-7 KJV
“And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not. Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed. Then said I, Lord, how long? And he answered, Until the cities be wasted without inhabitant, and the houses without man, and the land be utterly desolate, and the LORD have removed men far away, and there be a great forsaking in the midst of the land. But yet in it shall be a tenth, and it shall return, and shall be eaten: as a teil tree, and as an oak, whose substance is in them, when they cast their leaves: so the holy seed shall be the substance thereof.”
Isaiah 6:9-13 KJV
“Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.”

“because it is written, Be ye holy; for I am holy.”
1 Peter 1:16 KJV
It is not legalistic to be obedient to God. Obedience is loving God. All this is first by the faith choice of surrender wholly of self to God, by the power of the Holy Spirit. We have our part to do. If we meet God’s conditions by faith voice, put forth to do; God will bestow upon us His promised blessings and perform His thoughts toward us.
The temple has to be cleaned out, sanctified that the Holy Spirit dwell within. God will not share space in our mind (heart) with Satan, with demons (devils, unclean spirits). God is light and in Him is no darkness at all.
