How did the Old Testament prophets know what to write about Christ's birth, life, and death hundreds of years before Christ was born?

The concept of prophecies in the Old Testament is a matter of faith and interpretation. According to religious beliefs, it is believed that God communicated with the prophets, revealing to them elements of future events, including the birth, life, and death of Jesus Christ. This communication between God and the prophets was seen as a way to convey God's divine plan for humanity and to prepare people for the coming of the Messiah.

The Old Testament contains various prophetic books such as Isaiah, Jeremiah, and Micah, among others, which contain passages that are interpreted by Christians as referring to Christ. These prophecies are often seen as foreshadowing the coming of Jesus and are considered by believers as evidence of God's plan and the authenticity of Jesus' mission.

It is important to note that different scholars and religious traditions may have varying interpretations of these prophecies and their fulfillment in Jesus Christ. Some may argue that the passages were written after Jesus' birth and crafted to fit the narrative, while others interpret them as genuine predictions made centuries before his birth. Ultimately, the understanding of these prophecies and their connection to Christ is a matter of individual faith.
