What does Matthew 12:35 suggest about the source of one's words and actions?

Canonical Text

“‘The good man brings good things out of his good treasure, and the evil man brings evil things out of his evil treasure.’ ” — Matthew 12:35


Immediate Literary Setting

Matthew 12:33-37 forms Jesus’ rebuttal to Pharisaic accusations that He cast out demons by Beelzebul. Verses 33-35 employ fruit-tree imagery to expose a moral logic: one’s nature (tree/treasure) determines one’s expression (fruit/utterance). Verse 35 is the axiomatic climax, asserting that verbal and behavioral outputs originate in an inner “treasure” (thēsauros, storehouse) of either goodness or evil.


Key Terminology and Semantics

• “Good” (agathos) describes moral quality that accords with God’s character (Psalm 119:68).

• “Evil” (ponēros) denotes what is morally malignant and opposed to God’s will (Genesis 6:5).

• “Treasure” (thēsauros) pictures the heart as a vault storing dispositions, values, and motives (cf. Matthew 6:21).

• “Brings” (ekballō) stresses an outward, almost inevitable, emergence of what is stored within.


Biblical-Theological Thread: The Heart as Fountainhead

Scripture repeatedly identifies the “heart” (Heb. lēb; Gk. kardia) as the causal core of personality:

Proverbs 4:23: “Guard your heart…for it is the wellspring of life.”

Jeremiah 17:9: “The heart is deceitful above all things.”

Matthew 15:18-19: “Out of the heart come evil thoughts…These are what defile a man.”

Thus Matthew 12:35 affirms an ontological principle: conduct and speech are not random but proceed from a moral center. Genuine righteousness therefore requires internal transformation, not mere behavioral regulation.


Practical and Pastoral Applications

• Self-Examination: Regularly audit one’s conversational patterns to diagnose heart health (2 Corinthians 13:5).

• Discipleship: Train believers to meditate on Scripture, replacing corrupt stock with godly content (Philippians 4:8).

• Counseling: Behavioral issues trace back to heart idols; effective change targets core desires, not mere habits.


Evangelistic Invitation

If words betray a storehouse of sin, the remedy is not self-reform but surrender to the risen Lord who promises a new heart and eternal life (Romans 10:9-10; 2 Corinthians 5:17).
