John Wesley on Galatians 3:17

And this I say - What I mean is this. The covenant which was before confirmed of God - By the promise itself, by the repetition of it, and by a solemn oath, concerning the blessing all nations. Through Christ, the law which was four hundred and thirty years after - Counting from the time when the promise was first made to Abraham, Gen 12:2,3. Doth not disannul, so as to make the promise of no effect - With regard to all nations, if only the Jewish were to receive it; yea, with regard to them also, if it was by works, so as to supersede it, and introduce another way of obtaining the blessing.
