Proverbs 1:7 (NASB)
The fear of the Lord is the beginning of knowledge;
Fools despise wisdom and instruction.

Just by being interested enough to read this devotion, I would believe you fear the lord and are looking for knowledge.

I thought it might be interesting to look at the quadrant of knowledge and how we can match up scripture.

I have seen this quadrant pop up in Psychology and Speech courses I took in high school and college.

So to run through each of them. Let's start with What I know that I know.

2 + 2 =

I assume we all know the answer to this one, and we KNOW that we know it.

A good biblical verse that came to mind for me about it was:

Job 19:25 (NASB)
“As for me, I know that my Redeemer lives,
And at the last He will take His stand on the earth.

Next let’s move on to What I know that I Don’t Know.

What date is Jesus returning?

I think we all know that we don’t have that knowledge.

Mark 13:32(NASB)
But of that day or hour no one knows, not even the angels in heaven, nor the Son, but the Father alone.

Next we have What I Don’t know that I Know. Did you know that you can tell if water is hot or cold just by hearing it pour? I did not You can either test it yourself, or watch the following video:

Just goes to show how well God made us, that there are things we Know without knowing we do.

Psalm 139:13-14A(NASB)
For You formed my
inward parts;
You wove me in my
mother’s womb.
I will give thanks to You,
for I am fearfully and wonderfully made;

Next, What I Don’t know that I don’t know. Let's check out the following quote from Donald Rumsfeld, the 21st US Secretary of Defense from 2001-2006:

Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not now. But there are also unknown unknowns — the ones we don't know we don't know. And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones.
The absence of evidence is not evidence of absence, or vice versa.

We have a verse that tells us what non-Christians don’t know that they don’t know:

1 Corinthians 2:14(NASB)
But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised.

And we have a double hit in

Matthew 13:10-14(NASB)
And the disciples came and said to Him, “Why do You speak to them in parables?” Jesus answered them, “To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted. For whoever has, to him more shall be given, and he will have an abundance; but whoever does not have, even what he has shall be taken away from him. Therefore I speak to them in parables; because while seeing they do not see, and while hearing they do not hear, nor do they understand. In their case the prophecy of Isaiah is being fulfilled, which says, ‘You will keep on hearing, but will not understand; You will keep on seeing, but will not perceive;

"Hearing, but will not understand" ties us back to What I know that I don’t know.
"Seeing, but will not perceive" ties us back to What I Don’t Know that I don’t know.

But hopefully that passage does not apply to us.

If all of this is a little confusing, remember a verse that is a favorite of my father’s to quote:

Proverbs 17:28 (NASB)
Even a fool, when he keeps silent,
is considered wise;
When he closes his lips, he is considered prudent.
