2 Corinthians / Question
Paul says they walk in the flesh but do not wage war according to the flesh. He states their weapons are not of the flesh but have divine power to destroy strongholds, including taking thoughts captive to obey Christ. See 2 Corinthians 10:3–5.
In 2 Corinthians 10:3–6 Paul explains what kind of “battle” he is fighting. He admits he lives an ordinary human life, but insists his campaign is not run by merely human methods. Instead, his weapons have strength “before God” and are aimed at tearing down fortified resistance—ideas and attitudes that rise up against knowing God. This paragraph sits at the opening of a sharper, defensive section (chapters 10–13) where Paul addresses ongoing opposition and competing voices in Corinth. Just before this, he has been urging generous participation in the collection (chapters 8–9), but now he turns to how he will deal with challenges to his ministry.
Paul uses military language to explain a conflict connected to his ministry in Corinth (2 Corinthians 10:3–6). He admits he lives ordinary human life (“in the flesh”), but denies that his campaign runs on merely human resources, motives, or tactics (textual claim: he does not wage war “according to the flesh”).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with 2 Corinthians 10:3-5, then read the surrounding section so the answer stays connected to the passage's flow.
3For though we walk in the flesh, we don`t wage war according to the flesh;
4for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds,
5throwing down imaginations and every high thing that is exalted against the knowledge of God, and bringing every thought into captivity to the obedience of Christ;
