3 But I have a fear, that in some way, as Eve was tricked by the deceit of the snake, your minds may be turned away from their simple and holy love for Christ. 4 For if anyone comes preaching another Jesus from the one whose preachers we are, or if you have got a different spirit, or a different sort of good news from those which came to you, how well you put up with these things.

5 For in my opinion, I am in no way less than the most important of the Apostles. 6 But though I am rough in my way of talking, I am not so in knowledge, as we have made clear to all by our acts among you. 7 Or did I do wrong in making myself low so that you might be lifted up, because I gave you the good news of God without reward? 8 I took money from other churches as payment for my work, so that I might be your servant; 9 And when I was present with you, and was in need, I let no man be responsible for me; for the brothers, when they came from Macedonia, gave me whatever was needed; and in everything I kept myself from being a trouble to you, and I will go on doing so. 10 As the true word of Christ is in me, I will let no man take from me this my cause of pride in the country of Achaia. 11 Why? because I have no love for you? let God be judge. 12 But what I do, that I will go on doing, so that I may give no chance to those who are looking for one; so that, in the cause of their pride, they may be seen to be the same as we are. 13 For such men are false Apostles, workers of deceit, making themselves seem like Apostles of Christ. 14 And it is no wonder; for even Satan himself is able to take the form of an angel of light. 15 So it is no great thing if his servants make themselves seem to be servants of righteousness; whose end will be the reward of their works.

Matthew Henry's Commentary on 2 Corinthians 11:3-15

Commentary on 2 Corinthians 11:1-4

(Read 2 Corinthians 11:1-4)

The apostle desired to preserve the Corinthians from being corrupted by the false apostles. There is but one Jesus, one Spirit, and one gospel, to be preached to them, and received by them; and why should any be prejudiced, by the devices of an adversary, against him who first taught them in faith? They should not listen to men, who, without cause, would draw them away from those who were the means of their conversion.

Commentary on 2 Corinthians 11:5-15

(Read 2 Corinthians 11:5-15)

It is far better to be plain in speech, yet walking openly and consistently with the gospel, than to be admired by thousands, and be lifted up in pride, so as to disgrace the gospel by evil tempers and unholy lives. The apostle would not give room for any to accuse him of worldly designs in preaching the gospel, that others who opposed him at Corinth, might not in this respect gain advantage against him. Hypocrisy may be looked for, especially when we consider the great power which Satan, who rules in the hearts of the children of disobedience, has upon the minds of many. And as there are temptations to evil conduct, so there is equal danger on the other side. It serves Satan's purposes as well, to set up good works against the atonement of Christ, and salvation by faith and grace. But the end will discover those who are deceitful workers; their work will end in ruin. Satan will allow his ministers to preach either the law or the gospel separately; but the law as established by faith in Christ's righteousness and atonement, and the partaking of his Spirit, is the test of every false system.
