ἰσχύω

The Greek verb *ischýō* signifies having strength, force, or power, either literally or figuratively. It suggests an inherent capacity or ability to do something, to prevail, or to be effective. This strength can be physical, indicating robustness or vigor, or it can be a moral or spiritual power that enables one to overcome obstacles or maintain a position. The term often appears in contexts where there is a challenge, and the focus is on whether a person or thing possesses the necessary power to meet it. It often emphasizes the actual exercise of power and effectiveness in a given situation.

In the New Testament, *ischýō* is used in various ways. It can describe a physical inability, such as not being able to watch for one hour with Christ (Mark 14:37), or the inability of individuals to resist the wisdom of Stephen (Acts 6:10). It also conveys the idea of legal or ethical force, as seen in Hebrews 9:17, where a testament "is of force" after the death of the testator. Perhaps most notably, it appears in Philippians 4:13, where the Apostle Paul declares, "I can do all things through Christ which strengtheneth me," highlighting the spiritual endowment of power through Christ that enables believers to face any circumstance. This verse demonstrates a spiritual strength that transcends human limitations.

The semantic range of *ischýō* encompasses both the innate potential for strength and the active demonstration of that strength. It underlines the concept of capability, whether humanly derived or divinely bestowed. The use of *ischýō* often serves to highlight either human weakness in the face of a task or, conversely, the empowering presence of God that enables believers to accomplish what would otherwise be impossible. This reflects a significant theological emphasis on divine enablement in the life of faith.
