13For such men are false apostles, deceitful workers, masquerading as Christ`s apostles. 14No wonder, for even Satan masquerades as an angel of light. 15It is no great thing therefore if his ministers also masquerade as servants of righteousness, whose end will be according to their works.
16I say again, let no one think me foolish. But if so, yet receive me as foolish, that I also may boast a little. 17That which I speak, I don`t speak after the Lord, but as in foolishness, in this confidence of boasting. 18Seeing that many boast after the flesh, I will also boast. 19For you bear with the foolish gladly, being wise. 20For you bear with a man, if he brings you into bondage, if he devours you, if he takes you captive, if he exalts himself, if he strikes you on the face. 21I speak by way of disparagement, as though we had been weak. Yet however any is bold (I speak in foolishness), I am bold also.
