Topical Lexicon
Root Meaning and Biblical Imagery

The verb expresses the idea of making something wider so that it accommodates more. This broadening can be literal, as in expanding an object’s physical dimensions, or figurative, as in enlarging inner capacity for relationship, affection, or influence. The imagery evokes spaciousness, freedom, and generosity, contrasting cramped self-interest with an expansive spirit open to God and others.

Old Testament Background

Although the term itself is Greek, the concept of divine or moral “enlargement” is familiar in Scripture. The Lord “brought me out into a broad place” (Psalm 18:19) and gave Solomon “a breadth of understanding, as measureless as the sand on the seashore” (1 Kings 4:29). Spaciousness becomes a metaphor for deliverance and wisdom, preparing readers to grasp the New Testament’s figurative use for a heart opened wide by grace.

New Testament Usage

Matthew 23:5 – Religious Display

“They broaden their phylacteries and lengthen their tassels.”

Here the term exposes the hypocrisy of leaders who magnify religious accessories for public applause. The widening is cosmetic, masking hearts that remain narrow in mercy (Matthew 23:23). Jesus’ warning calls believers away from ostentatious spirituality toward genuine devotion.

2 Corinthians 6:11 – Apostolic Affection

“We have spoken freely to you, Corinthians. Our hearts are open wide.”

Paul testifies that his love for the church knows no restriction. He has made room for these believers in his inner life, modeling pastoral transparency and sacrificial care.

2 Corinthians 6:13 – Reciprocal Enlargement

“As a fair exchange—I speak as to my children—open wide your hearts also.”

The apostle appeals for mutual openness. Enlargement here is commanded, showing that believers participate actively in cultivating generous affections. It is not merely an emotional state but a Spirit-enabled choice to embrace others.

Theological Significance

1. Grace Expands the Heart: Salvation does more than pardon; it enlarges capacity for God’s purposes (Philippians 1:9).
2. Love as the Measure of Ministry: Genuine service is evaluated by the room one makes for others, not by external form (1 John 3:18).
3. Hypocrisy Contracts the Soul: Self-promotion focuses inward, shrinking spiritual vitality (James 3:14-16).

Historical Context of Practices Referred

Phylacteries (tefillin) were small leather boxes containing Scripture, worn during prayer per Deuteronomy 6:8. By Jesus’ day some Pharisees exaggerated their size to advertise piety. Tassels (tzitzit) were mandated reminders of God’s commands (Numbers 15:38-39) but likewise inflated for show. The Lord’s rebuke underscores that spiritual breadth is measured in mercy, not millimeters.

Ministry and Spiritual Application

• Personal: Ask the Spirit to enlarge compassion, replacing guardedness with Christlike openness (Romans 5:5).
• Corporate: Churches reflect God’s heart when they embrace diversity of background and maturity, refusing cliques and factionalism (Ephesians 4:1-3).
• Leadership: Shepherds cultivate broad hearts by transparent communication and self-giving service, inviting reciprocal trust (1 Thessalonians 2:7-8).
• Evangelism: A widened heart fuels mission, compelling believers to reach beyond comfort zones to those yet unreached (2 Corinthians 5:14).

Related Concepts in Scripture

– Generosity (Proverbs 11:25)

– Liberty in Christ (Galatians 5:1)

– The “large place” of divine deliverance (Psalm 31:8)

– The “wide gate” of ease that leads to destruction, contrasted with the narrow path of life (Matthew 7:13-14)

The verb therefore traces a moral topography: hearts shriveled by pride or fear versus hearts broadened by gospel love. The call echoes still—“open wide your hearts”—inviting every generation to live spaciously for the glory of God.
