17. Shall I hide from Abraham? Seeing that God here takes counsel, as if concerning a doubtful matter, he does it for the sake of men; for he had already determined what he would do. But he designed, in this manner, to render Abraham more intent upon the consideration of the causes of Sodom’s destruction. He adduces two reasons why He wished to manifest his design to Abraham, before he carried it into execution. The former is, that he had already granted him a singularly honorable privilege; the second, that it would be useful and fruitful in the instruction of posterity. Therefore, in this expression, the scope and use of revelation is briefly noted.
