The Bible is opposed to the the idea that God is unknowable.

What can be known about God is clear to them because he has made it clear to them. (Romans 1:19)
What can be known about God is clear, the Bible said. The reason for this is that God has made it clear. So, there is no reason for anybody who profess belief in God to think otherwise.
Why is it important that we possess knowledge about God? The Bible said, we need to know God to attain eternal life. Jesus said: "This is eternal life, that they may know you, the only true God..." (John 17:3)
To whom does the pronoun "you" refer? Is it the Son, the Holy Spirit, or the Father.
Jesus said the only true God is the Father.
These words spake Jesus, and lifted up his eyes and said, Father, the hour is come: glorify thy Son, that thy Son also may glorify thee: As thou hast given him power over all flesh, that he may give eternal life to all whom thou hast given him. And this is life eternal, to know thee, the only true God, and Jesus Christ, whom thou hast sent. (John 17:1-3)
Jesus Christ was sent by the only true God, that is none other than the Father, to make known to men about the only true God, the Father. So, the concept of trinity (a word coined and interpolated by Tertulian --a man declared by the Catholic Church as heretic) that there are three persons in one God and each person that comprises this God are all God, not only can never be found in the Bible but against it as well. Since the Father is the only true God, then Jesus Christ and the Holy Spirit are not Gods, therefore.
Furthermore, in John 1:1 the Bible said: "...the word was God." Therefore, knowing "the word" equals knowing God. What is this word that when we knew it equivalently we know God? "...the old commandment is the word which ye have heard from the beginning. (1 John 2:7)"
Is it enough that we know the commandments of God to say that we know God? No. The Bible said:
He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him; (1 John 2:4)
Therefore if your desire to know and understand God has something to do with the salvation of your soul when you die, then the Bible has stated it in no uncertain terms: The Father is the only true God and knowing Him requires that we obey His commandments.
Now, when you die you can no longer obey His commandments, neither you can know Him anymore.
For in death there is no memory of you; in the underworld who will give you praise? (Psalms 6:5)
So, when is the time to acknowledge the Father as the only true God and do all His commandments?
Whatever presents itself for you to do, do it with {all} your might, because there is no work, planning, knowledge, or skill in the grave where you're going. (Eccl 9:10)
The answer is now. Now that we are still alive.
