Meaning of "understanding" in 1 John 5:20?
What does "understanding" in 1 John 5:20 mean for our daily faith walk?

1 John 5:20

“And we know that the Son of God has come and has given us understanding so that we may know Him who is true; and we are in Him who is true—in His Son, Jesus Christ. He is the true God and eternal life.”


The Gift Described: What “understanding” Is

- Greek word διάνοια (dianoia): the mind, intellect, capacity to think through and discern truth.

- Not mere data; it is God-given insight that turns facts about Christ into living, relational knowledge.

- It is granted, not earned—“has given us.” We depend entirely on the Son’s initiative.


Why This Matters Every Day

- Assurance of truth: in a world of shifting claims, we stand on unshakable reality—“Him who is true.”

- Fellowship, not theory: understanding moves us from talking about God to abiding “in Him.”

- Confidence against deception: with Spirit-given insight, we discern counterfeit teachings (1 John 4:1-6).

- Eternal perspective: knowing “the true God and eternal life” anchors our hopes beyond temporal pressures.


Linked Passages That Deepen the Picture

- Luke 24:45 — “Then He opened their minds to understand the Scriptures.” Same divine initiative.

- Proverbs 2:6 — “For the LORD gives wisdom; from His mouth come knowledge and understanding.”

- Ephesians 1:17-18 — Paul prays for believers’ “eyes of your heart to be enlightened,” echoing the same gift.

- John 17:3 — “This is eternal life: that they may know You, the only true God, and Jesus Christ, whom You have sent.” Understanding and eternal life are inseparable.


Daily Walk: How to Live Out This Understanding

• Start with gratitude: each morning thank the Son for opening your mind to truth.

• Stay Word-saturated: since Scripture is flawless (Psalm 19:7), read and meditate, expecting further light.

• Obey promptly: understanding blossoms through practice (James 1:22-25).

• Test every voice: measure teaching, media, and inner thoughts against revealed truth (Acts 17:11).

• Cultivate Christ-centered fellowship: encourage others with truths you grasp, reinforcing shared certainty (Hebrews 10:24-25).

• Keep eternity in view: let the reality that you already possess “eternal life” shape priorities, finances, and relationships today.


Summary Snapshot

God the Son has graciously planted true comprehension in our minds so we can know, abide in, and represent the only true God. Receive the gift with humility, guard it diligently, and walk it out boldly—every decision, conversation, and challenge filtered through Spirit-given understanding of Jesus Christ, our eternal life.
