“6 Does the trumpet alarm sound in a city,
Without the people being afraid?
Does evil happen to a city,
And Yahweh hasn’t done it?
7 Surely the Lord Yahweh will do nothing,
Unless he reveals his secret to his servants the prophets.”
Amos 3:6-7 WEB

Of course, Liberalism believes in a “god” who does NOT intervene in His creation, so they would say there is nothing to reveal! However, Scripture consistently points to a God who constantly intervenes in our lives, makes sure we have food and clothes, may assist us or hinder or stop us in our endeavors. In fact James says,

“For you ought to say, “If the Lord wills, we will both live, and do this or that.””
Jas 4:15 WEB

So here is an all seeing God who guides events according to His purposes, and it is certainly consistent with the Bible message overall.

It is perhaps appropriate to admit that probably
MOST do NOT believe Amos 3:7!

This is a picture of an over-ruling God who constantly acts in history. And for God to let us know what He is doing? Many Christians even act blind, as if they have no idea what God does. But Amos 3:6-7 is a prophecy of what God will do, and says He does nothing unless He reveals it to His prophets. Further, Jesus says Scripture cannot be broken, Jn 10:35. Many other passages says essentially the same.

So how should we take these assertions.

God reveals through examples the ways He interactss
with men throughout history.

We read, or we should be reading, the accounts given the prophets of the ways God responds to certain types of actions. It is revealed to us how He acts in certain conditions. We know,

… “God resists the proud, but gives grace to the humble.”
Jas 4:6 WEB

And we know,

“The horse is prepared for the day of battle;
But victory is with Yahweh.”
Prov 21:31 WEB

So it is with many things.

But there are exceptional things which WILL
happen in history.

Things in which God will act in special ways, or allow stunning things to happen. Of these it says,

“Surely the Lord Yahweh will do nothing,
Unless he reveals his secret to his servants the prophets.”
Amos 3:7 WEB

Most of what we see in life and history is common, repeatable things, which happen in one form or another, time after time, and are revealed by God’s prophets. They may not be common to us, but they are common things in Bible history,

And of the astounding things which will lead up to the end of this present universe … these also are revealed by God’s prophets.

Are there still any things known only to God?

Yes. They belong to God. But the things revealed are sufficient so that we can be prepared, Deut 29:29. But we do need those revelations.

Instead of acting blind, we should,

“Knowing therefore the fear of the Lord, we persuade men, …”
2Cor 5:11 WEB
