Ephesians 4:15–16: Does the call to “grow up in every way” into Christ conflict with passages elsewhere that emphasize human fallibility and sinfulness?

Understanding the Passage (Ephesians 4:15–16)

“Instead, speaking the truth in love, we will in all things grow up into Christ Himself, who is the head. From Him the whole body, fitted and held together by every supporting ligament, grows and builds itself up in love through the work of each individual part.” (Ephesians 4:15–16)

In context, Paul urges believers toward maturity, using the metaphor of the human body growing. This call centers on Christ as the head, emphasizing reliance on Him for spiritual growth and unity.

The Tension Between Growth and Human Sinfulness

Throughout Scripture, human sinfulness is evident: “For all have sinned and fall short of the glory of God” (Romans 3:23). First John 1:8 likewise affirms that “If we say we have no sin, we deceive ourselves, and the truth is not in us”.

Yet this acknowledgment of pervasive sin does not negate the possibility—or the command—of spiritual growth. The biblical understanding maintains that believers still battle with sin, but simultaneously, they are called to “grow up in every way” into Christ. The call to growth is not a denial of fallibility. Rather, it is a directive that, amid ongoing imperfections, believers are sanctified by the Holy Spirit and gradually transformed.

Biblical Harmony in Sanctification

Scripture consistently weaves together the themes of human sin and the divine mandate for holiness. Paul’s reminder in Romans 6:11 provides a complementary balance: “So you too must count yourselves dead to sin, but alive to God in Christ Jesus.” Although sin remains a reality (1 John 1:10), the believer’s identity is reoriented; they are, by God’s grace, both forgiven and enabled to move toward Christlikeness.

This does not imply that believers become immediately sinless. Instead, it affirms that the power of Christ’s resurrection reshapes them. This process, often termed sanctification, is progressive. As the Philippians were reminded, “He who began a good work in you will continue to perfect it until the day of Christ Jesus” (Philippians 1:6). The theme is one of continuity from justification (being saved) to sanctification (growing in holiness) and ultimately glorification (the final removal of sin’s presence).

Growth Within the Community of Believers

Ephesians 4:15–16 focuses on a communal picture. Believers “grow up into Christ” not in isolation but together, “fitted and held together by every supporting ligament.” The synergy of the community plays a powerful role in growth:

1. Shared Support – As each member speaks truth in love, correction, encouragement, and instruction become instruments of sanctification.

2. Unified Purpose – The entire body builds itself up under Christ, reflecting the biblical principle that the Church functions best in unity (1 Corinthians 12:12–20).

3. Ongoing Process – The phrase “grows and builds itself up” underscores that the Christian life is dynamic, not static.

This communal dimension does not contradict human fallenness. On the contrary, it recognizes it. Each believer, while flawed, contributes uniquely to the edification of others—to confront sin, to carry burdens (Galatians 6:2), and to spur one another toward holiness (Hebrews 10:24–25).

Historical and Manuscript Evidence Supporting Ephesians

Early manuscript fragments (such as P46, dated around the late second to early third century) contain portions of Ephesians, demonstrating that Paul’s exhortations have been preserved accurately through centuries. These witnesses confirm that early believers engaged with the same message of progressive sanctification, highlighting how no conflict arises between growth and the reality of sin. Archaeological findings of early house churches around places like Ephesus support the historical backdrop of congregations that wrestled with these teachings in real-life community.

Theological Consistency and Practical Implications

Nothing in Ephesians 4:15–16 suggests that believers would reach a state of absolute perfection in this life (see also Philippians 3:12–14). Instead, the focus is on pursuing maturity under Christ’s headship:

• Continuous Growth: Believers are commanded to keep progressing, acknowledging that imperfection remains.

• Reliance on Christ: The completed work of Jesus is the basis for any spiritual advancement.

• Dependence on the Holy Spirit: Sanctification unfolds through reliance on God’s power, not human strength alone (Galatians 5:16–25).

The biblical narrative of the fall (Genesis 3) explains why sin persists in humanity. Nevertheless, the same overarching Scripture provides hope for transformation. This harmonizes with observed human behavior: individuals can exhibit moral and spiritual improvement while acknowledging temptations.

No Contradiction Between Growth and Sinfulness

In conclusion, believers still sin, but this does not diminish the call to mature “in every way” into Christ. Rather than conflicting, these truths provide a balanced biblical framework:

• Human fallibility underscores our ongoing need for grace.

• Divine calling to grow underlines that, while sinners by nature, believers are redeemed and equipped to reflect God’s holiness more fully over time.

Thus, Ephesians 4:15–16 complements—rather than contradicts—passages emphasizing human fallibility and sinfulness. The passage demonstrates that sin, though real, does not negate God’s work of sanctification, experienced corporately and individually.
