A primary verb meaning to lead, bring, or carry — whether guiding a person, driving an animal, or directing a course of action. It forms the root of many compounds: synagōgē (synagogue, a 'leading together'), stratēgos (general, a 'leading of an army'), and paidagōgos (tutor, a 'leading of a child'). In the passive, it can mean to be led or carried along.
The NT uses agō and its compounds to describe both divine and demonic leading. The Spirit leads Jesus into the wilderness (Matt 4:1), and believers are led by the Spirit (Rom 8:14; Gal 5:18). Paul declares, 'As many as are led by the Spirit of God, they are the sons of God' — making Spirit-led living the mark of divine sonship. Conversely, idolaters are described as 'carried away unto dumb idols' (1 Cor 12:2), and false teachers 'lead captive silly women' (2 Tim 3:6). Jesus was led to crucifixion (Luke 23:32). The theological question embedded in this verb is always: Who is leading you, and where?
