Link 1 John 5:20 & John 14:6 on truth.
How does 1 John 5:20 connect to John 14:6 about truth?

Setting the Scene: Two Verses, One Theme

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.”

John 14:6 — “Jesus answered, ‘I am the way and the truth and the life. No one comes to the Father except through Me.’”


Truth Is a Person

• Both passages treat truth not merely as a concept but as the very identity of Jesus Christ.

1 John 5:20 names Jesus “the true God,” while John 14:6 has Jesus declaring, “I am the truth.”

• The connection is straightforward: to meet Christ is to encounter objective, absolute, personal truth.


Knowing Truth Means Union with Christ

• 1 John highlights “we are in Him who is true,” stressing relational union.

John 14:6 shows the pathway into that union: “No one comes to the Father except through Me.”

• Together they teach that truth is entered, not simply studied.

John 17:3 echoes this: “Now this is eternal life: that they know You, the only true God, and Jesus Christ, whom You have sent.”


Understanding Granted by the Son

1 John 5:20 says Jesus “has given us understanding.” The mind is illuminated by the One who is truth.

• This fulfills John 1:9, “The true Light who gives light to every man was coming into the world.”

• Salvation, then, is both enlightenment and relationship—made possible only by Christ.


Exclusive and Comprehensive Truth

• Exclusive: John 14:6 insists there is no other way; 1 Timothy 2:5 adds, “For there is one God and one mediator between God and men, the man Christ Jesus.”

• Comprehensive: 1 John 5:20 concludes, “He is… eternal life.” All realities—way, truth, life—are wrapped up in Him (cf. Colossians 2:3).


Living Out the Truth

• Because we “are in Him,” believers bear witness to truth in daily conduct (Ephesians 4:25).

• The Spirit of truth indwells us (John 14:17), guiding into all truth (John 16:13) so our walk matches our confession.

• Anchored in the One who is true, we stand firm against error (2 John 1–2) and shine as “pillars and foundation of the truth” (1 Timothy 3:15).
