3 But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. 4 For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted--you may well put up with it!
5 For I consider that I am not at all inferior to the most eminent apostles. 6 Even though I am untrained in speech, yet I am not in knowledge. But we have been thoroughly manifested among you in all things. 7 Did I commit sin in humbling myself that you might be exalted, because I preached the gospel of God to you free of charge? 8 I robbed other churches, taking wages from them to minister to you. 9 And when I was present with you, and in need, I was a burden to no one, for what I lacked the brethren who came from Macedonia supplied. And in everything I kept myself from being burdensome to you, and so I will keep myself. 10 As the truth of Christ is in me, no one shall stop me from this boasting in the regions of Achaia. 11 Why? Because I do not love you? God knows! 12 But what I do, I will also continue to do, that I may cut off the opportunity from those who desire an opportunity to be regarded just as we are in the things of which they boast. 13 For such are false apostles, deceitful workers, transforming themselves into apostles of Christ. 14 And no wonder! For Satan himself transforms himself into an angel of light. 15 Therefore it is no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works.

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.
