Question

but that the same god has endowed us with senses, reason, and understanding, does not permit us to use them, and desires to acquaint us in any other way with such knowledge as we are in a position to acquire for ourselves by means of those faculties, that it seems to me i am not bound to believe... and this is precisely the case with astronomy. why does galileo believe god approves of his discoveries? god does not want galileo to believe in him. god created the stars, so he created astronomy. god showed galileo the workings of the universe. god gave humanity the ability to make such discoveries.

Explanation:

The text states that God endowed humans with senses, reason, and understanding. Galileo believes that if God didn't want humans to use these faculties (which led to his discoveries), God would have used another way to give knowledge. Since God gave these faculties, it implies approval of using them for discoveries.

Answer:

God gave humanity the ability to make such discoveries.
