The Holy Spirit has instructed Philip to make contact with the Ethiopian and he does so. Running alongside the chariot, he hears the eunuch reading from Isaiah. In those days, it was customary to read aloud, not silently when one read to their self. Philip asks him a simple question: “Do you understand what you are reading?” The English translation does not do justice to the original Greek wording. Philip’s question really asks the eunuch if what he is reading has any meaning for him, if what he is reading makes any sense.
The response is so telling! It is a response of frustration, discouragement and disappointment. “How can I, unless someone explains it to me?” Despite his apparent regalia and retinue, no one in Jerusalem had taken the time to answer his questions. No one helped quench his thirst for the knowledge of the One True God. He had a copy of the Scriptures, but could not understand what the words meant. He could read them, he was an educated man fluent in languages, but the meaning, the import, and the supernatural impact of the words eluded him.
There is a reason why the Bible says that only those who are spiritual can understand spiritual things. Until a person comes to submit their life to the Lord Jesus, the Bible depicts them as spiritually blind, unable to see or comprehend spiritual truths. They need the Holy Spirit to open their spiritual eyes and illuminate their minds. Often, the Spirit uses believers, like Philip, in that process.
The Ethiopian invites Philip up into his chariot and asks him a question about the passage he is reading. “Who is the prophet referring to?” Without being able to identify the subject talked about, a person cannot make a proper interpretation. Philip begins introducing the Ethiopian to Jesus through this passage. The Book of Isaiah was tailor-made for a person like this Ethiopian. It’s in Isaiah that many prophecies of Jesus’ birth and reign are found. It’s in Isaiah where one finds promises to eunuchs of their inclusion in God’s Holy Temple alongside other worshippers of God. Isaiah described God Himself, high and lifted up, as having compassion on people who have wandered away from the truth; who are like sheep.
Philip begins with the passage the Ethiopian is wrestling with and uses it as a springboard to tell the story of Jesus, God’s Messiah. As Philip expounds the meaning of what the Ethiopian was reading God’s Spirit illuminates his mind. Now, he realizes how a person is to worship God. Now, he realizes that it’s not at a Temple made by human hands but through faith in Jesus Christ that a person comes to approach God. As they pass by some water, he interrupts Philip to ask, “Is there anything that hinders me from being baptized right now?” He understands; he wants to identify with Jesus Christ and he desires to proclaim his newfound faith.
Water baptism was quite common in those days. In Judaism, it stood as a symbol for a Gentile’s repentance and conversion to Israel’s religion. In Christianity, it stands for each person’s repentance and as a symbol of his or her submission to Christ’s Lordship.
Philip baptizes the Ethiopian, which shows us an important picture. Philip, an olive skinned man, baptizes the Ethiopian, a black man, into the fellowship of the church. Philip, a former adherent to Judaism, and the Ethiopian, a former adherent to the religion of Meroe, become equal in standing before Christ. In Christ, racial barriers, national barriers, cultural barriers fall. Each person finds themselves equal at the foot of the Cross.
