I am preaching this morning on 2 Corinthians 10:1-6. In verses 4-6 Paul writes,
4 for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses. 5 We are destroying speculations and every lofty thing raised up against the knowledge of God, and we are taking every thought captive to the obedience of Christ,6 and we are ready to punish all disobedience, whenever your obedience is complete.”
Over 100 years ago, Alexander Maclaren wrote regarding the opposing fortresses of the gospel the following. Very few people today have the ability to do exposition as he did:
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.
There is the fortress of culture and the pride of it in which many of us are to-day entrenched against the Gospel. The attitude of mind into which persons of culture tend to fall is distinctly adverse to their reception of the Gospel, and that is not because the Gospel is adverse to culture, but because cultured people do not care to be put on the same level with publicans and harlots. They would be less disinclined to go into the feast if there were in it reserved seats for superior people and a private entrance to them. If the wise and prudent were more of both, they would be liker the babes to whom these things are revealed, and they would be revealed to them too. Not knowledge but the superciliousness which is the result of the conceit of knowledge hinders from God, and is one of the strongest fortresses against which the weapons of our warfare have to be employed.
There is the fortress of ignorance. Most men who are kept from Christ are so because they know neither themselves nor God. The most widely prevailing characteristic of the superficial life of most men is their absolute unconsciousness of the fact of sin; they neither know it as universal nor as personal. They have never gone deeply enough down into the depths of their own hearts to have come up scared at the ugly things that lie sleeping there, nor have they ever reflected on their own conduct with sufficient gravity to discern its aberrations from the law of right, hence the average man is quite unconscious of sin, and is a complete stranger to himself. The cup has been drunk by and intoxicated the world, and the masses of men are quite unaware that it has intoxicated them.
They are ignorant of God as they are of themselves, and if at any time, by some flash of light, they see themselves as they are, they think of God as if He were altogether such an one as themselves, and fall back on a vague trust in the vaguer mercy of their half-believed-in God as their hope for a vague salvation. Men who thus walk in a vain show will never feel their need of Jesus, and the lazy ignorance of themselves and the as lazy trust in what they call their God, are a fortress against which it will task the power of God to make any weapons of warfare mighty to its pulling down.
