Amós 3:7

Surely the Lord God will do nothing - In reference to the punishment, correction, or blessing of his people: -

But he revealeth his secret unto his servants the prophets - They are in strict correspondence with him, and he shows them things to come. Such secrets of God are revealed to them, that they may inform the people; that, by repentance and conversion, they may avoid the evil, and, by walking closely with God, secure the continuance of his favor.
