Mark 13:32 - Why doesn't the Holy Spirit know?
The Angel Gabriel said :The holy Spirit will come upon you, “The power of the Most High." (J. Moffat Luke 1:35) From the above words of Angel Gabriel to Mary we observe that the spirit is linked with the power of God, the" Divine power." Luke also wrote that Jesus commenced his ministry in the power of the spirit.
The Power of the Most High
Luke 1:31-32 NASB "And behold, you will conceive in your womb and
bear a son, and you shall name Him Jesus. 32 He will be great and will
be called the Son of the Most High; and the Lord God will give Him the
throne of His father David;
34" Mary said to the angel, “How can this be, since I am a virgin?” 35
"The angel answered her, "The holy Spirit will come upon you, the
power of the Most High will overshadow you; hence what is born will be
called holy, Son of God." (J.Moffat Luke 1:34,35)
And Luke says: Jesus started his ministry in the power of the spirit. " And Jesus returned to Galilee in the power of the Spirit, and news about Him spread through all the surrounding district." Luke 4:14 NASB
Jesus promised his Apostles that they will receive power when the holy Spirit comes upon you. "You will receive power when the holy Spirit comes upon you, and you will be my witnesses at Jerusalem, throughout all Judaea and Samaria, and to the end of the earth." (J. Moffat Acts 1:8)"
In his prayer, Paul spoke that the disciples will be filled with joy and power of the holy spirit.
" Now may the God of hope fill you with all joy and peace in
believing, so that you will abound in hope by the power of the Holy
Spirit."Romans 15:13 (NASB)
Divine inspiration through the spirit.
The Scriptures continuously reveal that God imparted divine inspiration through the spirit,to his servants and prophets, Peter wrote: For no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God. 2 Peter 1:21 (NASB)
Jesus was handed the scroll of Isaiah and applied to himself the words:
Luke 4:18 NASB : “The Spirit of the Lord is upon Me, Because He
anointed Me to preach the gospel to the poor. He has sent Me to
proclaim release to the captives, And recovery of sight to the blind,
To set free those who are oppressed."
Prophets were selected by God and appointed by means of holy spirit by which means they were inspired to prophesied.
Numbers 11:25 (NRSV)
25 "Then the Lord came down in the cloud and spoke to him, and took
some of the spirit that was on him and put it on the seventy elders;
and when the spirit rested upon them, they prophesied. But they did
not do so again."
God's spirit 'came upon them' at certain times, revealing the messages to be announced. This had a stirring effect upon them, impelling them to speak.
Micah 3:8 (NRSV)
8 "But as for me, I am filled with power, with the spirit of the
Lord, and with justice and might, to declare to Jacob his
transgression and to Israel his sin."
Impersonal attributes of the Holy Spirit
The holy spirit is spoken of in many ways that demonstrate that it is not a divine person. For example, it is referred to as a gift. "All the circumcised believers who came with Peter were amazed, because the gift of the Holy Spirit had been poured out on the Gentiles also." Acts 10:45 (NASB). We are told that the spirit can be quenched ,1Thess. 5:19
John the Baptist was filled with holy spirit while yet in his mothers's womb.
Luke 1:15 (NASB)
15 "For he will be great in the sight of the Lord; and he will drink
no wine or liquor, and he will be filled with the Holy Spirit while
yet in his mother’s womb."
We are told that God pours his spirit and his servants become filled with it, and that we are baptized with it:(Acts 2:17-33 NASB) )
“As for me, I baptize you with water for repentance, but He who is coming after me is mightier than I, and I am not fit to remove His sandals; He will baptize you with the Holy Spirit and fire. (Matthew 3:11NASB)
Such expression would not be made if the holy spirit were a divine person, in 1 John 5:7-8 for example, the spirit the water and blood ,testify and are in agreement. And Paul urges fellow Christians in Ephesus to become " filled with spirit," instead of with wine.
1 John 5:7-8 (NASB)
7 "For there are three that testify: 8 the Spirit and the water and
the blood; and the three are in agreement."
Ephesians 5:18 (NASB)
18 "And do not get drunk with wine, for that is dissipation, but be
filled with the Spirit."
The holy spirit is described by other titles, "the holy spirit of promise," "the pledge of our inheritance," and the "spirit of wisdom."
Ephesians 1:13-17 (NASB)
13 "In Him, you also, after listening to the message of truth, the
gospel of your salvation—having also [b]believed, you were sealed in
Him with the Holy Spirit of promise, 14 who is given as a pledge
of our inheritance, with a view to the redemption of God’s own
possession, to the praise of His glory.
15 "For this reason I too, having heard of the faith in the Lord Jesus
which exists among you and your love for all the saints, 16 do not
cease giving thanks for you, while making mention of you in my
prayers; 17 that the God of our Lord Jesus Christ, the Father of
glory, may give to you a spirit of wisdom and of revelation in the
[g]knowledge of Him."
The Holy Spirit is absent in visions of God’s throne.
In Acts 7:54-57 where we read about the stoning of Stephen.
55 "But being full of the Holy Spirit, he gazed intently into heaven
and saw the glory of God, and Jesus standing at the right hand of God;
56 and he said, “Behold, I see the heavens opened up and the Son of
Man standing at the right hand of God.” 57 But they cried out with a
loud voice, and covered their ears and rushed at him with one
impulse."
Daniel describes his vision of heaven.(Read Daniel 7:9-14)
Daniel 7:13-14 NASB
The Son of Man Presented.
13 “I kept looking in the night visions, And behold, with the clouds
of heaven One like a Son of Man was coming, And He came up to the
Ancient of Days And was presented before Him. 14 “And to Him was
given dominion, Glory and a kingdom, That all the peoples, nations
and men of every language Might serve Him. His dominion is an
everlasting dominion Which will not pass away; And His kingdom is one
Which will not be destroyed.
In the Book of revelation, the holy spirit as a divine person is completely absent from its pages. The book describes “a new heaven and new earth” (Revelation 21:1) wherein “the tabernacle of God is with men, and He will dwell with them” (Revelation 21:3). Christ the Lamb is also present (Revelation 21:22). The Holy Spirit as a distinct person, however, is again absent—another inexplicable oversight .
Personification does not make the spirit a person.
Unlike English, other languages like Greek , Hebrews , Spanish have noun "genders" some nouns are "masculine" some are "feminine" and others are "neuter" something like we say in English ; Emperor a "he" and Empress a "she." For example, The sun namely "hos helios" is masculine, The sea namely "he thalassa" is feminine and The spirit namely " to pneuma is neuter. The pronoun "hos" is used for masculine nouns, "he" for feminine and "to" is used for neuter nouns.
The holy spirit is referred to by a neuter noun , and accordingly is never spoken with personal pronouns in Greek. It is a "which," not a "who." It is and "it" not a "he."
For example for lack of vitamin D , your doctor may ask you to go out in the sun to get sunshine vitamin D , and may refer that the sun (helios -masculine) will be your "helper" (paracletos). Obviously the sun is not a person, neither is the holy spirit (pneuma-neuter), which serves as a "helper,"
Conclusion.
As noted from the many passages , the spirit is the Divine Power of God, that God uses, to help and guide his servants, it is spoken as filling people, John the Baptist was said to filled with it whilst in his mother's womb.
The Bible speaks of God as accomplishing work with his fingers, such as the writing of the Ten Commandments (Deuteronomy 9:10) and creating of the heavens:
"When I consider Your heavens, the work of Your fingers, The moon and
the stars, which You have ordained."(Psalm 8:3 NASB)
The Christian Greek Scriptures help us understand such symbolic usage, Matthew's account explains that Jesus expelled demons by "God's holy spirit" and Luke’s telling us that it was by "God's finger."
Matthew 12:28 (NASB)
28 "But if I cast out demons by the Spirit of God, then the kingdom of
God has come upon you."
Luke 11:20 (NASB)
20 "But if I cast out demons by the finger of God, then the kingdom of
God has come upon you."
An going back to the question (Mark 13:32) -" Why doesn't the Holy Spirit know?" Simply the holy spirit does not know because ,it is the Divine Power ,the angel Gabriel knows best, when he said to Mary: The holy Spirit will come upon you, "The power of the Most High"(J Moffat Luke 1:35)
