The Greek word asthenéō, represented by G770, means to be feeble in any sense. It appears 39 times across 35 unique verses in the Bible, encompassing a range of meanings from being physically sick or diseased to being spiritually or morally weak. Its base definition is "to be feeble (in any sense):--be diseased, impotent folk (man), (be) sick, (be, be made) weak."
The lexical root of asthenéō (G770) lies in asthenḗs (G772), a compound of the privative alpha (ἀ-) and sthénos (strength). This etymological breakdown reveals its core meaning as "without strength" or "lacking inherent power." This nuance suggests not merely a temporary ailment, but a fundamental inability or incapacity, whether physical, moral, or spiritual. When scripture describes someone as asthenéō, it often points to a state where natural human resources are insufficient, thereby highlighting the need for external, often divine, intervention or support. This inherent lack of strength is crucial for understanding its theological implications, particularly in areas where human effort proves futile.
In scripture, G770 is used in several key contexts. It frequently describes physical illness, as when Jesus commands his disciples to "heal the sick" Matthew 10:8 or when Lazarus is described as being sick John 11:1. It is also used to describe the "great multitude of impotent folk" at the pool of Bethesda John 5:3. The term extends beyond physical ailment to describe spiritual or moral frailty. Paul speaks of one who is "weak in the faith" Romans 14:1 and warns believers not to become a stumbling block to those who are weak 1 Corinthians 8:9. The law itself is described as being weak through the flesh, unable to save on its own Romans 8:3.
Beyond general descriptions of illness, asthenéō also captures specific instances of prolonged or severe physical affliction, emphasizing the sustained need for divine intervention or compassionate care. For example, the nobleman's son in Capernaum was described as being sick (John 4:46), and Trophimus was left at Miletum sick by Paul (2 Timothy 4:20), indicating a persistent condition rather than a fleeting one. The term also appears in the context of communal responsibility, where believers are called to remember the weak, as Paul exhorted them to "support the weak" in his farewell to the Ephesian elders (Acts 20:35). This highlights the practical outworking of Christian love in caring for those who are physically or otherwise unable to care for themselves, extending the concept of weakness beyond mere spiritual frailty to tangible, daily needs.
Several related words provide a broader understanding of weakness and strength:
- G769 asthéneia (feebleness (of mind or body); by implication, malady; morally, frailty): As the noun form, it is directly linked to G770. It is used to describe the weakness in which Christ's power is made perfect 2 Corinthians 12:9.
- G102 adýnatos (unable, i.e. weak... impossible): This term highlights inability. It is used in Romans 8:3 to describe what the law could not do because it was weak G770 through the flesh.
- G1415 dynatós (powerful or capable... strong): This word serves as the direct opposite of being weak. Paul contrasts the two, stating, "for when I am weak G770, then am I strong" 2 Corinthians 12:10.
- G2323 therapeúō (to wait upon menially... to relieve (of disease)): This word for healing is often the response to the condition of being sick G770, as seen in Jesus's command to his disciples Matthew 10:8.
- G772 asthenḗs (without strength): As the adjectival root of G770, this term describes the state of being weak, feeble, or without strength, from which the verb asthenéō is derived.
The theological weight of G770 is significant, touching on both human frailty and divine power.
- The Ministry of Compassion: The frequent call to heal the sick (Matthew 10:8, Luke 9:2) establishes physical healing as a core component of Christ's ministry and a demonstration of God's power over disease and suffering.
- Responsibility within the Community: The concept of the brother who is weak in faith creates a duty for other believers to provide support Acts 20:35 and to be careful not to wound their conscience or cause them to stumble (Romans 14:21, 1 Corinthians 8:12).
- The Paradox of Strength in Weakness: Paul radically redefines weakness as a conduit for God's power. He declares that he takes pleasure in his infirmities, because "when I am weak G770, then am I strong" 2 Corinthians 12:10. This principle is rooted in Christ, who was crucified in weakness G769 but lives by the power of God 2 Corinthians 13:4.
- Faith Overcoming Weakness: The concept of G770 also serves to contrast with robust faith. Abraham, for instance, is commended because he was "not weak in faith" (Romans 4:19), implying that a strong faith can overcome natural physical limitations and doubts. This suggests that while human beings are inherently prone to weakness, faith provides a spiritual strength that enables them to transcend physical or circumstantial feebleness, trusting in God's promises even when human capabilities asthenéō.
G770 asthenéō fundamentally describes a state of being "without strength," derived from the privative alpha and sthénos (strength). This inherent lack of power manifests across various dimensions, from pronounced physical illness and debility, as seen in the "impotent folk" at Bethesda John 5:3 and Lazarus's sickness John 11:1, to profound spiritual or moral frailty. It captures not merely a temporary ailment but a condition where human capabilities are insufficient, highlighting a dependency on external aid.
In scriptural application, G770 frequently denotes sustained conditions of physical suffering, such as the nobleman's son who was sick John 4:46 or Trophimus whom Paul left sick at Miletum 2 Timothy 4:20, underscoring the persistent reality of human vulnerability. This physical feebleness often elicited the compassionate ministry of Christ and His disciples, who were commanded to "heal the sick" Matthew 10:8. Furthermore, the term extends into the communal life of believers, establishing a clear responsibility to "support the weak" Acts 20:35 and to avoid actions that might cause a "weak brother" to stumble or wound their conscience 1 Corinthians 8:9, 1 Corinthians 8:12.
Theologically, G770 carries profound implications. It illuminates the paradox where human weakness becomes the very canvas for divine power, as articulated by Paul who took pleasure in infirmities, declaring, "when I am weak, then am I strong" 2 Corinthians 12:10. This principle is rooted in Christ's own experience, crucified in weakness G769. Moreover, asthenéō also serves as a benchmark for faith; Abraham's commendation for "not being weak in faith" Romans 4:19 demonstrates that spiritual strength can transcend physical limitations. Ultimately, the term underscores God's deep engagement with human frailty, offering healing, support, and the transformative power that makes His strength perfect in our inherent lack of it.
