Amen!
Also, He's the one who ministers the Word unto us. He convicts, He comforts, etc. as well.
Let's take a few examples of what Jesus said keeping in mind how Jesus defined the Father as God the Spirit in John 4:23,24.
Speaking against Jesus doesn't carry the same consequence as does speaking against the Spirit because speaking against Jesus isn't the same thing as speaking against the Spirit. So how about the Father? No mention of the Father in Matthew 12:31,32 because it would be redundant to mention the Father with the Holy Spirit. The Father is the Spirit.
Matthew 12
31Therefore I tell you, every sin and blasphemy will be forgiven men, but the
blasphemy against the Spirit will not be forgiven. 32Whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the one to come.
Don't lose focus on John 4:23,24 Why did Jesus say no one knows the son except the Father and no one knows the Father except the son? Jesus isn't implying the Spirit doesn't know the Father and son because the Father is the Spirit. It would be redundant to include the Spirit here since the Spirit is already being talked about.
Matthew 11
27All things have been entrusted to Me by My Father.
No one knows the Son except the Father, and no one knows the Father except the Son and those to whom the Son chooses to reveal Him.
Now do you understand why Jesus explicitly defined the Father as the true God alone? (John 17:3)
Why Paul said there is one God, the Father? (1 Cor. 8:6)
Why the prophets defined YHWH as the Father? (Malachi 2:10, Isaiah 64:8)
No one knows the thoughts of God except the Spirit does not mean to exclude the Father from knowing the thoughts of God because the Father is the Spirit. (1 Corinthians 2:10,11)
And more. Start with that and let's see how it goes.
