In the lead up to His crucifixion, Jesus stood before Pontius Pilate and said these words:
“You say that I am a king. For this purpose I was born and for this purpose I have come into the world— to bear witness to the truth. Everyone who is of the truth listens to my voice.” (John 18:37)
In the very next verse Pilate replies with perhaps the most important question one could ever ask:
“What is truth?”
Interestingly, the answer has already been given, by Jesus Himself, in the preceding chapter:
“Sanctify them in the truth; your word is truth.” (John 17:17)
The Greek word for “truth” found in John 17:17 is not an adjective (meaning “your word is true”) but a noun (alÄ“theia, “truth”). This means that God's Word does not simply conform to some external standard of truth, but that it is truth itself; that is, it embodies truth and is therefore the standard of truth against which everything else must be tested and compared.
It is sometimes said that truth is that which conforms to reality. Very often this statement is posited with the intent of offering a justification for truth without God. However, it raises a pressing question: “How do we know what is real?”
It is important to understand that without God we have only ourselves to appeal to. However, if we employ our senses and reasoning to justify our senses and reasoning we argue in a vicious circle. Appealing to ourselves to validate ourselves is self-refuting, and therefore nonsensical.
So, what is truth?
Truth is that which conforms to the mind of God.
Without an objective standard for truth, there can be no truth. Truth is never subjective. Truth is that which conforms to the mind of God because truth comes from God, indeed, He Himself is the objective standard for truth.
Soli Deo Gloria!
