ἀσθενέω

The Greek verb *asthenéō* carries the primary meaning "to be weak" or "to be feeble." This weakness can manifest in various ways, encompassing physical infirmity, as when someone is sick or diseased. It can also extend to a spiritual or moral feebleness, describing those who are immature in their faith or lack conviction. The term highlights a general state of lacking strength, whether in body, spirit, or understanding. This semantic range is crucial for comprehending its diverse uses in the New Testament.

In the New Testament, *asthenéō* is frequently used to describe physical illness, much like our English word "sick." However, it also takes on significant theological weight when applied to spiritual conditions. Paul, in particular, uses this verb to speak of those who are "weak in faith" (Romans 14:1) or those whose conscience is not yet fully developed, making them vulnerable to stumbling (1 Corinthians 8:9-11). This spiritual weakness is not necessarily a moral failing, but rather a state of immaturity or susceptibility.

Paul also employs *asthenéō* in a profoundly personal and paradoxical way, famously stating, "when I am weak, then I am strong" (2 Corinthians 12:10). Here, his physical or personal weaknesses become the very locus where God's power is most evident. This demonstrates that human frailty, when surrendered to God, can become a conduit for divine strength. This usage elevates the concept beyond mere physical or spiritual deficiency to a profound theological truth about God's strength being perfected in human weakness.
