The sermon recounts the story of Jesus walking on the sea, Peter's attempt to do the same, and his subsequent sinking due to doubt and fear. The sermon highlights that while many Christians aspire to be spiritual "honor roll" students, we often struggle with faith mixed with doubt. The sermon emphasizes the importance of fixing our eyes on Jesus rather than our circumstances, as He never takes His eyes off us, illustrating that Jesus's intervention and constant presence are the essence of the gospel's good news.
