Col 3:9 & Eph 4:25: Truthfulness link?
How does Colossians 3:9 connect with Ephesians 4:25 on truthfulness?

The call to truthfulness in Colossians 3:9

“Do not lie to one another, since you have taken off the old self with its practices.”

• A clear, direct command: lying is out of bounds for every believer.

• The reason: we have “taken off” (a completed, decisive act) the old, sin-dominated self. Lying belongs to the wardrobe we left behind.


Linking Colossians 3:9 and Ephesians 4:25

“Therefore each of you must put off falsehood and speak truthfully to his neighbor, for we are members of one another.”

• Both verses pair a negative (“put off” lying) with a positive (“speak truthfully”).

• Colossians frames it in terms of the old vs. new self; Ephesians frames it in terms of body life—“members of one another.”

• Together they show that truthfulness is essential both for personal transformation and for healthy community.


Why truthfulness matters: theological roots

• God is “the God who cannot lie.” (Titus 1:2)

• Jesus said, “I am the way and the truth.” (John 14:6)

• Satan “is a liar and the father of lies.” (John 8:44)

• When we tell the truth, we reflect God’s character; when we lie, we echo the enemy’s voice.


Practical outworking of putting off the old self

• Evaluate speech: Am I shading facts, exaggerating, withholding needed information?

• Replace deceit with candor: say the true thing in a loving way (Ephesians 4:15).

• Remember identity: I am now “in Christ,” so lies no longer fit who I am.

• Lean on the Spirit: He is “the Spirit of truth” (John 16:13) who empowers honest words.

Steps for cultivating a truthful life

1. Memorize Colossians 3:9 and Ephesians 4:25; let them reshape reflexes.

2. Invite accountability—give a trusted believer permission to ask about integrity.

3. Practice immediate correction: if a false word slips out, own it at once.

4. Keep short accounts with God—confess lies quickly (1 John 1:9).

5. Celebrate truth in others; encourage honest speech to build a culture of integrity.

Truthful words are not optional extras; they are the natural vocabulary of a life made new in Christ.
