General Revelation

The Judeo-Christian faith is a revealed religion.

That is, we know what we know about God, as it has been recorded in the Bible, because God has chosen to make Himself known to His creation.
God has chosen to reveal Himself to mankind.
Theologians identify two kinds of revelation.
General Revelation or Universal Revelation

General revelation is also called universal revelation because this is revelation that God has made available to everyone everywhere.

This comes is three ways.

1. Nature (creation)

Psalm 19:1-3
The heavens declare the glory of God;
And the firmament shows His handiwork.
2 Day unto day utters speech,
And night unto night reveals knowledge.
3 There is no speech nor language
Where their voice is not heard.

Creation speaks of a creator.
We know that out of nothing, nothing comes.

2. God has made Himself known through history.

The formation and preservation of the Jewish people is evidence that God exists. Though persecuted in virtually every country they have ever lived, the Jewish people remain. The fact that you will be hard pressed to find an ancient historian that will deny that Jesus Christ existed is evidence of how God has revealed Himself in history.

3. God has revealed Himself by virtue of a God-consciousness, or by what some call a religious nature in humanity.

This is why wherever you find man you find religion.
In all civilizations from all time, you find people instinctively reaching out to connect with God as they understand Him to be.
Along with this religious nature are moral qualities of a commonly shared knowledge of right and wrong or what we call a conscience.
