Ambrosiaster
AD 400
It is clear that only God knows everything and it is only he who lacks nothing, because everything comes from him. No one can understand or measure this knowledge, because the inferior cannot comprehend what is superior to it. Jewish believers could not understand that the salvation of the Gentiles could be God’s plan and will. Likewise, it seemed unlikely and incredible to the Gentiles that the Jews, who had not believed, could be converted or accepted as believers. Commentary on Paul’s Epistles.
