The answer is: Isaiah

Acts 8:32 - this is from Isa 53.

In Acts 8, we encounter a captivating character—the Ethiopian eunuch—who is not just a powerful official in charge of the treasury of the Queen of Ethiopia but also a sincere seeker of spiritual truth. His reading from the book of Isaiah, specifically Isaiah 53, reveals a poignant moment etching a bridge between a prophecy and a gospel message.

Isaiah 53 is a remarkable section often referred to as the "Suffering Servant" passage. It speaks of a figure unfamiliar with personal sin, who bears injustice and suffering for the sake of others. This ties beautifully to both the life and message of many spiritual traditions that emphasize selflessness and the weight of compassion.

Interestingly, it's worth noting that Isaiah is also significant in the Jewish prophetic tradition, making this connection especially rich. The Ethiopians have a long-standing reverence for Isaiah. Even today, the Christopher World Mission is active in Ethiopia, spreading Biblical knowledge. So, when the eunuch hears Philip’s explanation of the good news, he’s already steeped in the spirituality that Isaiah portrays.

As the eunuch welcomes understanding, his transformative experience invites us all to reflect on how we approach scriptural texts. Often, our insight comes from a heart that is open and eager to understand, breaking conventions of ethnicity and status. His baptism right after this encounter illustrates a fresh beginning; it serves as a resounding reminder that no matter where we start, knowledge and revelation can lead us towards a greater understanding of humanity and the divine. What an inspiring template for learning and growth!
