to conquer, to overcome, to win out: to come through a struggle as the victor.
At its core this verb names winning a contest. In the wider Greek world it was the language of armies that won battles, athletes who took the prize wreath, and litigants who won their case in court, and it could also describe mastering one's own desires. In the first century it was charged far beyond a plain dictionary sense: it was the vocabulary of empire, the boast on Caesar's coins and the name of the winged goddess of Victory whose image was everywhere. Any reader hearing it pictured the strong crushing the weak.
What makes the New Testament use of the word remarkable is that its writers take this language of force and turn it inside out. The decisive victory is won by Jesus, and he wins it not by overpowering his enemies but by dying. Revelation drives the point home: the Lion who has conquered turns out to be a slain Lamb. So when the word is then applied to Christians, their conquering is not military or competitive at all. They overcome by belonging to the one who already won, by holding to their confession of him, and by refusing to give in even when it costs them their lives.
The senses below are not different words but different settings for this one idea of winning out:
- Christ's own finished victory
- the believer's share in it through faith
- the everyday moral version of overcoming evil with good
- a courtroom vindication
- turned around, the hostile power that appears to win by killing the faithful
Across all of them the basic meaning holds steady; only who is winning, and how, changes.
