Does only the Holy Spirit know the mind of God?

Answer:

"Yet we do speak wisdom among those who are mature; a wisdom, however, not of this age nor of the rulers of this age, who are passing away; but we speak God's wisdom in a mystery, the hidden wisdom which God predestined before the ages to our glory; the wisdom which none of the rulers of this age has understood; for if they had understood it they would not have crucified the Lord of glory; but just as it is written, 'Things which eye has not seen and ear has not heard, and which have not entered the heart of man, all that God has prepared for those who love Him.' For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God. For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God" (I Corinthians 2:10-11).

The wisdom that Paul taught does not come from this particular era or from leading men of this age. Neither of these will last. This wisdom comes from God and had been hidden from people in the past. Paul is not claiming that he was preaching in a mysterious fashion or in some fashion that purposely hid God’s message from people. He is only referring to the fact that God keeps parts of His plan hidden until the proper time (Romans 16:25-26; Ephesians 3:1-10; Colossians 1:26; I Timothy 3:16). But God’s purpose had been laid out before time. This isn’t a last-minute thought or a passing fad. It wasn’t built upon things in this world since it was planned before the world began. Nor can it be claimed that the leading men in the world shaped it because they didn’t even realize it existed. If they had, they would have not crucified the Christ (Acts 3:17). It is not that they could not have known. The evidence was right before them (John 5:36; 10:25), but they were not willing to accept what they saw.

The wisdom which God has revealed to His people could not have been invented by men. Referring to Isaiah 64:4 Paul points out that it wasn’t something seen before, heard before, or even thought about in the past. But God prepared these very things for the people He loved. The context of the quote, Isaiah 64:1-9, shows that what was longed for was a revelation of God's method for saving people from their sins. We are privileged to know these things because God has shown them to us through the work of the Holy Spirit (John 14:26; 16:13-14). The Spirit of God understands all these things because He has access to the depths of God’s mind, just as the spirit of a man knows his innermost thoughts (Proverbs 14:10; 20:27; 27:19). This is something no man has the right to claim (Romans 11:33-34).

Thus, Paul is not say that only the Holy Spirit had access to God's mind to the exclusion of the Father and the Son. He is saying that one man does not know what another man is thinking, so how could a mere man claim to know what God is thinking? What we know of God's thoughts are only the things God has chosen to reveal to men through the Holy Spirit.

"In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through Him, and apart from Him nothing came into being that has come into being. In Him was life, and the life was the Light of men" (John 1:1-4).

When you read the creation account in Genesis 1, you see God and the Spirit mentioned, which naturally leaves a person wondering where the Son was. John fills in the God. On each day of creation, we find "And God said ..." John is telling us that Jesus was the word that created the Universe. "For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities--all things have been created through Him and for Him" (Colossians 1:16).
