What Is Truth? A Biblical Study of the Words of Jesus

With a Subtitle: A Biblical study of why Jesus calls Himself the truth, and how to live in it.

A brief Excerpt: The Greek word for truth, aletheia, means the unconcealed. This Biblical word study traces how Jesus embodies truth in John 14:6 and what it means to live in it.

Editor’s note – The question “What is truth?” is famous for being thrown at Jesus by a Roman governor who then walked away without waiting for the answer. We run this piece because it does what Pilate would not: it stays in the room long enough to listen. The author’s word study on aletheia is careful and devotional rather than merely academic, and it lands where every honest inquiry into truth eventually must – at the feet of the One who called Himself the truth. Read it slowly; the riddle is worth solving.

The Riddle and Its Answer

In a world of illusions and shifting sands,
An unchanging pillar steadfastly stands.
Through the fog it cuts with a guiding light,
Revealing what’s real amidst the night.
What is this beacon, so clear and bright,
That cuts through the falsehoods with unwavering might?

"Jesus said to him, 'I am the way, and the truth, and the life. No one comes to the Father except through me.'" - John 14:6

The answer to the riddle is Jesus, the truth. In John 14:6, Jesus declares Himself as the embodiment of truth, in addition to being the way and the life. This verse highlights Jesus as the ultimate source of truth, guiding believers through the complexities of life.

The Greek Term and Its Meaning

The Greek term for truth, “aletheia” (ἀλήθεια), carries a rich and multifaceted meaning. Derived from the root “lanthano” (λανθάνω), which means “to hide or conceal,” and combined with the prefix “a-” that negates the hiding, “aletheia” means “that which is revealed” or “unconcealed.” This concept of truth encompasses several dimensions:

• Truth as Spoken: “Aletheia” represents the opposite of falsehood, referring to something factually correct or accurate in speech.¹
• The truth of Idea and Reality: Beyond mere factual accuracy, “aletheia” represents the truth of concepts and the reality of things as they truly are. It aligns with the philosophical view of truth as the revelation of the authentic nature of something.²
• Sincerity: It emphasizes authenticity and genuineness, not only in words but in character and intention, reflecting a moral and ethical commitment to truthfulness.³
• Truth in the Moral Sphere: “Aletheia” is also associated with righteousness and moral integrity, implying a life lived in accordance with divine or moral truth, manifesting ethical behavior.⁴
• Simplicity: “Aletheia” refers to transparency and honesty, reflecting a lack of deception or manipulation.⁵
• Divine Truth Revealed to Man: “Aletheia” also signifies the truth divinely revealed to humanity.⁶

Editor’s note – That the Greek word for truth literally means the unconcealed, the un-hidden, is worth sitting with. In a culture that treats truth as something we construct or negotiate, Scripture presents it as something revealed – already there, waiting to be uncovered. We do not invent the truth; we are found by it.

Jesus as “aletheia”

Jesus, identifying as “aletheia,” presents Himself as the truth in all its aspects.⁷ As the spoken word, He is the opposite of falsehood, offering genuinely correct and precise discourse that guides humanity.⁸ In terms of idea and reality, Jesus reveals the authentic nature of God and, consequently, of the world, showing how things are in their essence.⁹ His life and teachings reflect sincerity and authenticity, evidencing a character and intention that reflect a moral and ethical commitment to truthfulness.¹⁰ Furthermore, Jesus exemplifies righteousness and moral integrity, inviting all to live according to divine truth, thus manifesting ethical behavior aligned with God’s will.¹¹ His simplicity is reflected in His transparency and honesty, which are free of deception or manipulation.¹² Finally, Jesus is the divine truth revealed to humanity, showing the way to salvation and a proper relationship with the Creator.¹³

Editor’s note – Notice how the author refuses to soften the claim. If Jesus is truth itself, then truth is not finally a proposition to be argued but a Person to be known. That is also why John 14:6 ends where it does: no one comes to the Father except through Him. Exclusive, yes – but only because reality is.

Conclusion

Jesus’ declaration of being “aletheia” means that He is the ultimate, definitive, and complete revelation of divine reality, showing the nature of God and His will, contrasting with the falsehoods and illusions of the world. His life, teachings, and sacrifice are the definitive expressions of “aletheia,” revealing the fullness of God’s plan and the true path to salvation.

Editor’s note – The author wisely does not stop at definition. Truth that is only understood has not yet done its work. The six days that follow turn doctrine into practice, which is exactly the movement Jesus describes: knowing the truth, and being set free by it.

Living out “Aletheia”

Make an effort to align your life with the “aletheia” revealed by Jesus.

• Day 1: Read and meditate on John 14:6 and related passages like John 8:32 (“And you shall know the truth, and the truth shall make you free”). Reflect on what it means for Jesus to be the embodiment of truth.
• Day 2: Identify an area in which you may be living in hypocrisy or falsehood. Commit to facing this area with honesty and openness.
• Day 3: Practice speaking truthfully in your conversations. Avoid exaggeration, half-truths, or deceptive speech.
• Day 4: Reflect on how speaking the truth can strengthen your relationships and reflect the character of Jesus.
• Day 5: Ensure that your actions align with your spoken words and that you act with integrity and authenticity, reflecting the truth of Jesus.
• Day 6: Share the truth with others.

A Word from the Editor
Jesus promised that we would “know the truth, and the truth shall make you free.” Freedom, in His economy, is not the absence of every limit but the presence of what is real. To live in aletheia is to stop managing illusions and to rest in the One who cannot lie.
