Okay, now
I understand about The Holy Spirit,

Jesus Christ (Yeshua Hamashiach ) called Satan the father of lies, while The Holy Spirit (Ruach Ha-Kodesh) is the Spirit of truth.

John 8:44
King James Version
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

The Holy Spirit opposes the anti-Holy Spirit because they are completely opposite to each other; The Holy Spirit is Spirit of God (Ruach Elohim) and the anti-Holy Spirit is spirit of Satan.

John 16:13
King James Version
13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.

Genesis 1:2
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.

Bereshis 1:2
2 And the earth was tohu vavohu (without form, and void); and darkness was upon the face of the deep. And the Ruach Elohim was hovering upon the face of the waters.
