Matthew Poole and continuators on Galatians 3:8

8 And the Scripture foreseeing that God would justifie the heathen through faith preached before the gospel r unto Abraham, saying, In thee shall all nations be blessed .

The Holy Ghost in Scripture, (by whose inspiration the Scripture was written) foreseeing, or knowing the Councels and designs of God, that the Heathen, (when the fulness of times as to them should come,) should be justified through Faith in Christ; preached the same Doctrine before unto Abraham, so as it is no new Doctrine; the Gospel which we now preach unto you, was long since revealed unto Abraham; who saw Christ's day, and rejoiced. Ioh. 8.56.

To prove which, he quoteth the promise, Gen. 12.3. where God tells Abraham, That i[illegible: 1 letter] him all the Nations of the Earth should be blessed; which quotation of it by the Apostle in this place informeth us, that it is to be understood of those Spiritual Blessings which are in Christ Jesus. For all the Nations of the Earth were no otherwise blessed in Abraham, then as Christ, (who is called the desire of all Nations, and he in whom the Gentiles should trust, and a light to enlighten the Gentiles,) descended from Abraham.
