Romans 9:3 - Wesley's Explanatory Notes

I could wish — Human words cannot fully describe the motions of souls that are full of God. As if he had said, I could wish to suffer in their stead; yea, to be an anathema from Christ in their place. In how high a sense he wished this, who can tell, unless himself had been asked and had resolved the question? Certainly he did not then consider himself at all, but only others and the glory of God. The thing could not be; yet the wish was pious and solid; though with a tacit condition, if it were right and possible.
