Importance of love in faith?
What does "This is the first and greatest commandment" imply about the importance of love in faith?

Old Testament Roots: The Shema (Deuteronomy 6 : 5)

The wording is an exact citation of Deuteronomy 6:5. Excavations at Qumran (4QDeut f, dated c. 150 BC) contain the Shema verbatim, confirming textual stability centuries before Christ. For Israel the Shema was recited twice daily; its placement inside mezuzot and tefillin unearthed at Masada underscores its centrality. By declaring this commandment “first and greatest,” Jesus affirms continuity between the covenants, establishing that authentic faith has always been relational, not merely ritual.


“First” (πρώτη) and “Greatest” (μεγάλη): Hierarchy of Moral Obligation

“First” assigns priority; “greatest” assigns magnitude. Jesus signals that any theology, ethic, or practice lacking supreme love for God is disordered. In rabbinic debates (cf. b. Mak. 24a) 613 mitzvot were ranked; Christ ends the debate by rooting all commands in a single core, echoed by Paul: “Love is the fulfillment of the law” (Romans 13:10).


Theological Significance: Love as the Essence of Covenant Relationship

God is love (1 John 4:8). Humanity, bearing His image, is created for relational reciprocity. The first commandment reveals God’s intent: a people who mirror His character. Sin is essentially failure to love Him (Jeremiah 2:2-5). Redemption, therefore, restores the capacity and desire to love (Ezekiel 36:26-27).


Christological Fulfillment

Jesus embodies perfect obedience to the first commandment. The Gospels repeatedly note His constant communion with the Father (Mark 1:35; John 17:24-26). The cross is the climactic act of loving God’s will (Matthew 26:39) and loving sinners (John 15:13), proving that divine love is self-giving. Resurrection vindicates that love is stronger than death, anchoring salvation in a living Person, not abstract principle (Romans 5:8-10).


Pneumatological Empowerment

“God’s love has been poured out into our hearts through the Holy Spirit” (Romans 5:5). Believers are not merely commanded to love; they are enabled supernaturally. Pentecost demonstrates that heart transformation precedes ethical transformation (Acts 2:42-47).


Eschatological Permanence

Faith and hope will give way to sight, but “the greatest of these is love” (1 Corinthians 13:13). Revelation portrays eternal worship marked by undiluted love for the Lamb (Revelation 5:9-14). Thus the first commandment governs not only present ethics but everlasting destiny.


Ethical Dimensions: Heart, Soul, Mind

Heart (καρδία) designates the control center of affections and decisions; soul (ψυχή) encompasses life and identity; mind (διάνοια) addresses intellect and reason. Comprehensive love excludes compartmentalized religiosity. Study, emotion, vocation, and recreation alike become arenas for glorifying God (1 Corinthians 10:31).


Community and Mission Implications

When love for God is supreme, love for neighbor flows naturally (Matthew 22:39). The early church’s communal life—attested by Luke’s historiography and corroborated by pagan observers like Pliny the Younger (Ep. 96)—functioned as persuasive apologetic evidence. Modern evangelism likewise gains credibility when it radiates genuine God-centered love.


Patristic Witness

Ignatius of Antioch encouraged believers “to love the one who has died for us,” linking martyrdom to the first commandment (Letter to the Smyrnaeans 4). Augustine called love “the weight that carries my soul” (Confessions 13.9), interpreting all biblical commands as expressions of ordered love (ordo amoris).


Philosophical and Behavioral Analysis

Empirical studies on worship and well-being (e.g., Harvard T. H. Chan School, 2016) show that intrinsic religious commitment correlates with reduced depression and greater life satisfaction. From a behavioral science standpoint, humans flourish when aligned with a transcendent object of ultimate worth, precisely what the first command secures.


Archaeological Corroboration of Worship Centrality

The Ketef Hinnom silver amulets (7th century BC) bear the priestly blessing (Numbers 6:24-26), illustrating personal devotion predating the Exile. At Tel Arad, a Judean temple inscription invokes Yahweh, demonstrating decentralized yet Yahweh-focused worship. These finds reinforce that loving devotion, not mere cultic formality, characterized true faith.


Practical Outworking: Cultivating Supreme Love

1. Scripture immersion (Psalm 119:97).

2. Prayerful communion (Psalm 63:1).

3. Corporate worship (Hebrews 10:24-25).

4. Obedient action (John 14:21).

5. Intellectual renewal (Romans 12:2).

Each discipline is means, not end; the end is delight in God Himself.


Summary

Calling the Shema “the first and greatest commandment,” Jesus establishes love for God as the fountainhead of faith, ethics, community, mission, and eternal hope. This command is foundational because it reflects God’s nature, fulfills the law, empowers human flourishing, and endures forever.

Why is this commandment considered the 'greatest' by Jesus in Matthew 22:38?
