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

I was recently discussing the overall message of the Gospel with a friend of mine, and we started talking about Matthew 28:19. We were exploring the concept of evangelism and the Great Commission given by Jesus to His disciples before ascending to heaven. We were particularly intrigued by the verse that says, "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." We wondered how this verse relates to the broader message of the Gospel. I'm curious to hear your thoughts on this and understand how you perceive the significance of Matthew 28:19 in light of the Gospel's central themes. Your insights would be greatly appreciated.
