5 For I reckon that in nothing I am behind those who are in surpassing degree apostles. 6 But if [I am] a simple person in speech, yet not in knowledge, but in everything making [the truth] manifest in all things to you. 7 Have I committed sin, abasing myself in order that ye might be exalted, because I gratuitously announced to you the glad tidings of God? 8 I spoiled other assemblies, receiving hire for ministry towards you. 9 And being present with you and lacking, I did not lazily burden any one, (for the brethren who came from Macedonia supplied what I lacked,) and in everything I kept myself from being a burden to you, and will keep myself. 10 [The] truth of Christ is in me that this boasting shall not be stopped as to me in the regions of Achaia. 11 Why? because I do not love you? God knows. 12 But what I do, I will also do, that I may cut off the opportunity of those wishing [for] an opportunity, that wherein they boast they may be found even as we. 13 For such [are] false apostles, deceitful workers, transforming themselves into apostles of Christ. 14 And [it is] not wonderful, for Satan himself transforms himself into an angel of light. 15 It is no great thing therefore if his ministers also transform themselves as ministers of righteousness; whose end shall be according to their works.

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.
