1 Corinthians 2:10 these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God.
I know what I know because God has revealed it to me.
1 Corinthians 8:2 If anyone imagines that he knows something, he does not yet know as he ought to know.
Everything else is imagination. The root word of imagination is image. It is perception, how we “see” things, the mind’s interpretation of sensory input. When I had my stroke, the translation centers of my brain that renders optical signals from the eye and allows the brain to understand what is seen, I discovered I had blind spots due to dead brain cells. My translation was broken.
The mind is a wonderful tool and takes what is missing and fills in the blind spots to make sense of what is seen. One day as I looked at the trees in the distance at a curve in the road the trees parted like a curtain and a truck appeared through the opening. What I imagined was replaced by another image. Ahead on the road, following traffic, I saw an RV and as I approached that vehicle I discovered it was not an RV but rather a colorful box truck.
I had to learn not to trust what I saw until I was close enough to cause those blind spots to be small enough that they did not need to be filled in by my brain’s memories.
In the same way, I know what I know because the Holy Spirit reveals it to me and everything else is just my mind trying to make sense of what I do not know to be true.
Daniel 2:19 Then the mystery was revealed to Daniel in a vision of the night. Then Daniel blessed the God of heaven.
No matter how the truth is revealed to us, praise God. Blessed be our true God.
Matthew 16:15-17 English Standard Version
15 He said to them, “But who do you say that I am?” 16 Simon Peter replied, “You are the Christ, the Son of the living God.” 17 And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.
Be not proud when we think we have it all figured out. God the Father alone reveals in our hearts that the Son is the Christ.
Again, intellect does not save us. God does. Our eyes can deceive us.
