Semantic range (Thayer / BDAG)

To be alive (physically / biologically), the standard medical-physical sense. To draw breath; to function biologically.
To return to life / be raised, the resurrection sense; passive constructions (cf. zaō used of Christ post-resurrection: Luke 24:5, 23, "He is alive"; Acts 1:3, 25:19; Rom 6:10).
To live (spiritually / eschatologically), the qualitative-life sense; zōē / zaō as the redeemed life shared with God. Distinct from bios (the everyday physical life), zaō / zōē often denote the higher / divine / eternal life.
To live (manner of life), to conduct oneself, to walk in a particular way (Rom 14:7-8, "none of us lives for himself... whether we live or die, we are the Lord's").
To live forever / eternally (present-active force when applied to God / Christ), the divine-eternal-life sense (the "living God" idiom; Christ as "the living one").

Theological force, the resurrection-side word

Zaō is the verb on the other side of the cross, the verbal correspondent to G3498 - nekros in the resurrection-axis word-pair. Where nekros names the state Christ entered and overcame, zaō names the state Christ now occupies and shares.

Christ as "the living one." The post-resurrection idiom is consistently in the present-active: Christ lives. The angel at the empty tomb: "why do you seek the living (zōnta) among the dead (nekrōn)?" (Luke 24:5). Christ to John on Patmos: "I was dead (egenomēn nekros), and behold, I am alive forever and ever (zōn eis tous aiōnas tōn aiōnōn)" (Rev 1:18). The grammatical present captures the enduring state of resurrection-life, not a one-time event in the past but the standing reality of the risen Christ.

The "I AM the life" claim. Jesus's egō eimi sayings (cf. G1510 - eimi) include "I am the resurrection and the life (hē zōē)" (John 11:25). The verbal zaō is intimate with the substantive zōē (life). The whole Christ-as-life Christology in the Gospel of John (1:4, "in Him was life"; 5:26, "as the Father has life in Himself, so He gave to the Son also to have life in Himself"; 14:6, "I am the way, the truth, and the life") sits on this lexical-conceptual base.

The believer's life "in Christ." Paul's most concentrated treatment is Galatians 2:20: "I have been crucified with Christ; and it is no longer I who live (zō), but Christ lives in me (zē en emoi Christos); and the life (zōē) which I now live in the flesh I live by faith in the Son of God." The zaō verb here carries the entire Pauline-mystical-union doctrine: the Christian's continuing existence is Christ-living-in-the-Christian, life in the resurrected sense, not merely biological subsistence.

The "living God" idiom. Theos zōn, the living God, distinguishes the God of Israel from idols (which are dead, Ps 115:4-7; Jer 10:5). This OT idiom (1 Sam 17:26, 36; Pss 42:2, 84:2; Hos 1:10; Dan 6:20) carries directly into the NT (Mt 16:16, Peter's confession, "the Christ, the Son of the living God"; Heb 9:14, 10:31, 12:22; Rev 7:2). The living God gives life; the dead idols cannot.

Patristic / scholarly note

The Gospel of John's Christ-as-life Christology is the dominant patristic lens for zaō / zōē. Cyril of Alexandria (Commentary on John) develops the life-from-life tradition: the Father has life aseity (in Himself), and grants the Son to have life in Himself (John 5:26), an eternal-generation pattern that secures Christ's full deity while preserving the Father-Son relation. Athanasius (De Incarnatione 33-44), Christ's resurrection is the enduring state of life that defeats death once for all.

In Reformed theology, John Murray and Anthony Hoekema develop the zaō / nekros contrast in the ordo salutis: the spiritually-dead are made spiritually-alive (zōopoieō) by monergistic divine action; this is regeneration. Sinclair Ferguson (The Christian Life), the believer's continuing experience of Christ-living-in-me (Gal 2:20) is the daily working out of the resurrection-life.

The theos zōn tradition (the living God) is one of the OT's strongest polemics against idolatry: idols are dead (Ps 115:4-7; Jer 10), they have eyes that don't see, ears that don't hear, mouths that don't speak. The living God is the antithesis: the God who is and acts in the present tense. The Christian apologetic appeal to the resurrection trades on this: the living Christ is the proof that the living God acted in history (Acts 17:31, "He has furnished proof... by raising Him from the dead").
