The gospel is a two pronged approach to Salvation through Jesus the Messiah (promised annointed one). Firstly most know that Jesus came to take away the sins of the world, and most Christians embrace this part of his work. He is also coming again to establish the Kingdom of God on earth. Most of Jesus teaching during his ministry on earth was to tell us about the Kingdom of God, what it is like and what one must do to be a part of it. He is coming again as King of Kings this next time, not as a lamb to be slaughtered again, but as a glorious victorious conqueror over sin and death. He will come because if he did not, no flesh would be saved alive. He will come, will you be ready?
