II Corinthians 10:3

For--Reason why they should regard him "beseeching" them (Co2 10:2) not to oblige him to have recourse to "bold" and stern exercise of authority. "We walk IN the flesh," and so in weakness: but not "ACCORDING TO the flesh" (Co2 10:2). Moreover, though we WALK in it, we do not WAR according to it. A double contrast or antithesis. "They who accuse us of walking after the flesh, shall find [to their cost] that we do not war after the flesh; therefore compel us not to use our weapons" [ALFORD].

There was no place in which the apostle Paul met with more opposition from false apostles than at Corinth; he had many enemies there. Let not any of the ministers of Christ think it strange if they meet with perils, not only from enemies, but from false brethren; for blessed Paul himself did so. Though he was so blameless and inoffensive in all his carriage, so condescending and useful to all, yet there were those who bore him ill-will, who envied him, and did all they could to undermine him, and lesson his interest and reputation. Therefore he vindicates himself from their imputation, and arms the Corinthians against their insinuations. In this chapter the apostle, in a mild and humble manner, asserts the power of his preaching, and to punish offenders (Co2 10:1-6). He then proceeds to reason the case with the Corinthians, asserting his relation to Christ, and his authority as an apostle of Christ (Co2 10:7-11), and refuses to justify himself, or to act by such rules as the false teachers did, but according to the better rules he had fixed for himself (Co2 10:12 to the end).

10:3-5 A military metaphor enforces Paul’s rebuttal: Paul’s weapons have divine power over spiritual strongholds (see 4:3-4).
