Abraham Piper

The philosophical definition of "Knowledge"
Is a "Justified, True, BELIEF."
And perhaps the cat is sitting on the chair,
Or perhaps you are hallucinating it.
Some people do.
Therefore, it can be credibly said
That any amount of knowledge
Rests on the belief that it is so,
And then the justification by witnesses
And the verity of its objectivity.

Jesus is the LORD.
I can believe in Him
And also Know He is LORD.
As John says several times,
Which you failed to point out,
"Now this is eternal life: 
"that they know you, the only true God, 
"and Jesus Christ, whom you have sent."

To know God and Jesus
Implies that salvation comes by way
Of having knowledge that He is LORD.
