For the majority of my life I've wondered why we are given the story of Philip and the Ethiopian. At first glance, it's a strange story that involves the angel of the Lord, Philip, and an Ethiopian in a chariot. However, when we dive into the text we see there's more to the story. The Ethiopian has attempted to worship at Jerusalem only to be told that he can't. Unfortunately, for the Ethiopian, he did not meet all the standards necessary to worship in the fullest sense at the Temple.
While traveling back, God sends Philip to engage with the Ethiopian to teach a crucial lesson that is as applicable today as it was then. Although he's been rejected by the religious authority of his time, he's been accepted by Jesus. It is through his interaction with Philip that the Ethiopian learns of Jesus and is told the gospel. This newfound understanding of the gospel fills the Ethiopian with the courage to move forward into a relationship with Christ.
I believe the most beautiful moment in Acts 8 is when the Ethiopian realizes that nothing can get in the way of him being baptized and in turn welcomed into the Kingdom of God. Philip responds in the way that we all should by getting out of the chariot with the Ethiopian and into the water with him. He doesn't analyze or deny, he accepts. When need to be like Philip and be willing to step into the water with those that have been rejected rather denying their access.
