'Holy' in the Bible

But ye have an unction from the Holy One, and ye know all things.

And everyone who has this hope in him makes himself holy, even as he is holy.

The one who habitually keeps His commandments [obeying His word and following His precepts, abides and] remains in Him, and He in him. By this we know and have the proof that He [really] abides in us, by the Spirit whom He has given us [as a gift].

By this we know [with confident assurance] that we abide in Him and He in us, because He has given to us His [Holy] Spirit.

This is He who came through water and blood [His baptism and death], Jesus Christ—not by the water only, but by the water and the blood. It is the [Holy] Spirit who testifies, because the Spirit is the truth. [He is the essence and origin of truth itself.]

For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
