'Casting 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; and being in readiness to avenge all disobedience, when your obedience shall be fulfilled.'--2 COR. x. 5 and 6 (R.V.).
None of Paul's letters are so full of personal feeling as this one is. It is written, for the most part, at a white heat; he had heard from his trusted Titus tidings which on one hand filled him with a thankfulness of which the first half of the letter is the expression; but there had also been tidings of a very different kind, and from this point onwards the letter is seething with the feelings which these had produced. There was in the Corinthian Church a party, probably Judaisers, which denied his authority and said bitter things about his character. They apparently had contrasted the force of his letters and the feebleness of his 'bodily presence' and speech. They insinuated that his 'bark was worse than his bite.' Their language put into plain English would be something like this, 'Ah! He is very bold at a distance, let him come and face us and we shall see a difference. Vapouring in his letters, he will be meek enough when he is here.'
These slanderers seem to have thought of Paul as if he 'warred according to flesh,' and it is this charge, that he was actuated in his opposition to the evils in Corinth by selfish considerations and worldly interests, which seems to have set the Apostle on fire. In answer he pours out quick, indignant questionings, sharp irony, vehement self-vindication, passionate remonstrances, flashes of wrath, sudden jets of tenderness. What a position for him to have to say, 'I am not a low schemer; I am not working for myself.' Yet it is the common lot of all such men to be misread by little, crawling creatures who cannot believe in heroic self-forgetfulness. He answers the taunt that he 'walked according to the flesh' in the context by saying, 'Yes, I live in the flesh, my outward life is like that of other men, but I do not go a-soldiering _according_ to the flesh. It is not for my own sinful self that I get the rules of my life's battle, neither do I get my weapons from the flesh. They could not do what they do if that were their origin: they are of God and therefore mighty.' Then the metaphor as it were catches fire, and in our text he expands the figure of a warfare and sets before us the destruction of fortresses, the capture of their garrisons, and the leading of them away into another land, the stern punishment of the rebels who still hold out, and the merciful delay in administering it. It has been suggested that there is an allusion in our text to the extermination of the pirates in Paul's native Cilicia which happened some fifty or sixty years before his birth and ended in destroying their robber-holds and taking some thousands of prisoners. Whether that be so or no, the Apostle's kindled imagination sets forth here great truths as to the effects which his message is meant to produce and, thank God, has produced.
I. The opposing fortresses.
The Apostle conceives of himself and of his brother preachers of Christ as going forth on a merciful warfare. He thinks of strong rock fortresses, with lofty walls set on high, and frowning down on any assailants. No doubt he is thinking first of the opposition which he had to front in Corinth from the Judaisers to whom we have referred, but the application of the metaphor goes far beyond the petty strife in Corinth and carries for us the wholesome lesson that one main cause which keeps men back from Christ is a too high estimate of themselves. Some of us are enclosed in the fortress of self-sufficiency: we will not humbly acknowledge our dependence on God, and have turned self-reliance into the law of our lives. There are many voices, some of them sweet and powerful, which to-day are preaching that gospel. It finds eager response in many hearts, and there is something in us all to which it appeals. We are often tempted to say defiantly, 'Who is Lord over us?' And the teaching that bids us rely on ourselves is so wholly in accord with the highest wisdom and the noblest life that what is good and what is evil in each of us contribute to reinforce it. Self-dependence is a great virtue, and the mother of much energy and nobleness, but it is also a great error and a great sin. To be so self-sufficing as not to need externals is good; to be so self-sufficing as not to need or to see God is ruin and death. The title which, as one of our great thinkers tells us, a humourist put on the back of a volume of heterodox tracts, 'Every man his own redeemer,' makes a claim for self-sufficiency which more or less unconsciously shuts out many men from the salvation of Christ.
