How does Matthew 28:19 relate to the overall message of the Gospel?

I recently joined a Bible study group at my church, and we've been diving into the book of Matthew. As we explore the different themes and messages in this Gospel, I can't help but wonder about the significance of Matthew 28:19. This particular verse states, "Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." The Gospel of Matthew has been highlighting Jesus' ministry and teachings, emphasizing his role as the Messiah and the fulfillment of Old Testament prophecies. Along the way, we have learned about the Kingdom of Heaven, the importance of faith, and the call to spread the good news. With this context in mind, I am curious to understand how Matthew 28:19 fits into the overall message of the Gospel. Why is Jesus instructing his disciples to go and make disciples of all nations? How does this command relate to the themes we have explored so far? I look forward to hearing your thoughts on this matter and gaining a deeper understanding of the message conveyed through Matthew 28:19.
