John Wesley on Isaiah 65:1

I am, &c. - This in the primary sense of this text, is a prophecy of the conversion of the Gentiles, upon the rejection of the Jews; for their contempt and crucifying of Christ, cannot be doubted by any, who will not arrogate to themselves a greater ability to interpret the prophesies of the Old Testament, than St. Paul had, who, Rom 10:20, expressly so interprets it, and applies it, which shews the vanity of the Jews in their other interpretations of it. Sought - The word signifies properly a diligent enquiry in things relating to God. Asked not - That in times past made no enquiry after me; l am now found by them that formerly sought me not. I said - I invited whole nations by the preaching of my gospel to behold me, and that with importunity, doubling my words upon them, and this I did unto a nation not called by my name, with whom I was not in covenant.
