In the past

In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son

Hebrews 1:1,2

In the past God spoke to our ancestors; through Isaiah, Jeremiah, Ezekiel, Daniel, Hosea, Joel, Amos, Obediah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, Malachi, at many times and in various ways

The above are the prophets who wrote books in the Old Testament. However, there are many others who are either referred to as prophets or acted as prophets, for example, Noah, Abraham, Isaac, Joseph, Moses, Aaron, Miriam and around thirty others

But in these last days he has spoken to us by his Son

In the past God revealed himself through letter, word, sentence and paragraph; through diction, noun, adjective and verb; through poetry, history, story and song. But now God speaks by flesh, bone, spirit and mind; by heart, voice, soul and body. The exalted Son revealing the Father of Heaven to the children of earth
