Hebrews 12:15

Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble [you], and thereby many be defiled;

Looking diligently {G1983} lest {G3361} any man {G5100} fail {G5302} of {G575} the grace {G5485} of God {G2316}; lest {G3361} any {G5100} root {G4491} of bitterness {G4088} springing {G5453} up {G507} trouble {G1776} you, and {G2532} thereby {G1223}{G5026} many {G4183} be defiled {G3392};

See to it that no one misses out on God’s grace, that no root of bitterness springing up causes trouble and thus contaminates many,

See to it that no one falls short of the grace of God, and that no root of bitterness springs up to cause trouble and defile many.

looking carefully lestthere beany man that falleth short of the grace of God; lest any root of bitterness springing up trouble you, and thereby the many be defiled;

Commentary

Hebrews 12:15 serves as a powerful warning and exhortation to the Christian community, emphasizing the importance of spiritual vigilance and the destructive nature of unaddressed sin, particularly bitterness.

Context

This verse is nestled within a larger section of Hebrews (chapters 11-12) that encourages perseverance and endurance in the Christian race. Having just highlighted the "great cloud of witnesses" (Hebrews 12:1) and the necessity of fixing one's eyes on Jesus, the author shifts to practical instructions for living out this faith. The immediate preceding verses speak of divine chastening as a sign of sonship and the pursuit of peace and holiness (Hebrews 12:14). Verse 15 thus presents specific dangers that could hinder this spiritual journey and defile the community.

Key Themes

  • Diligence and Vigilance: The phrase "Looking diligently" (Greek: episkopountes) implies careful oversight, watching over oneself and others within the community. It's a call to active, watchful care to prevent spiritual decline.
  • Failing of the Grace of God: This doesn't necessarily mean losing salvation, but rather failing to appropriate or benefit from God's ongoing supply of grace. It's about falling short of the life God intends, perhaps through neglect, unbelief, or a return to former ways. The Greek word hustereō means to be behind, to fall short, or to come too late. It highlights a state of spiritual deficiency. The writer has previously warned against drawing back unto perdition, reinforcing the need for steadfastness and reliance on God's sustaining power.
  • The Root of Bitterness: This vivid metaphor, "root of bitterness" (Greek: rhiza pikrias), likely alludes to Deuteronomy 29:18, where a "root that beareth gall and wormwood" refers to idolatry leading to defilement. Here, it refers to a deep-seated resentment, unforgiveness, or a grudge that, if left unchecked, grows and poisons the individual and the community. It's a warning against allowing personal grievances to fester.
  • Corporate Defilement: The most sobering aspect is that one person's bitterness can "trouble [you], and thereby many be defiled." Unresolved bitterness is not a private sin; it has a contagious, corrupting effect, spreading discord and spiritual contamination throughout the fellowship. This underscores the interconnectedness of believers and the importance of individual spiritual health for the well-being of the entire body of Christ.

Linguistic Insights

The term "fail of the grace of God" uses the Greek verb hustereō, which means to be behind, to lack, or to fall short of something. It suggests a failure to attain or maintain the benefits and power of God's grace in one's life, leading to spiritual deficiency rather than necessarily a loss of salvation itself. The phrase "root of bitterness" (rhiza pikrias) is a powerful agricultural metaphor, indicating something hidden yet growing, capable of producing noxious fruit. The verb "defiled" (miainō) means to stain, pollute, or contaminate, emphasizing the pervasive and corrupting nature of bitterness within a community.

Practical Application

Hebrews 12:15 calls believers to active self-examination and mutual accountability. We are urged to:

  • Guard our hearts: Regularly assess for any seeds of resentment, anger, or unforgiveness that might be taking root. As Proverbs 4:23 advises, "Keep thy heart with all diligence; for out of it are the issues of life."
  • Embrace forgiveness: Actively choose to forgive those who have wronged us, preventing bitterness from taking hold. Paul encourages believers to "let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice" in Ephesians 4:31.
  • Live in grace: Continually rely on God's grace for strength, perseverance, and transformation. Recognize that it is by God's grace that we are saved and sustained (Ephesians 2:8).
  • Care for the community: Be vigilant not only for personal spiritual health but also for the well-being of fellow believers, offering support, encouragement, and, when necessary, gentle correction to prevent the spread of spiritual decay.

This verse serves as a timeless reminder that individual spiritual health profoundly impacts the collective, and unaddressed bitterness is a serious threat to the vitality and purity of the church.
