The church's primary mission is to preach the Gospel, make disciples who will preach the Gospel, and make more disciples. This is the “great commission.” However, making disciples has an objective: to bring people into the Kingdom of God. The Kingdom of Heaven and the Kingdom of God are used more than one hundred times in the New Testament. The book of Matthew uses the terms “Kingdom of Heaven” and “Kingdom of God” interchangeably. The other three gospels use the term “Kingdom of God” exclusively. The Hebrew word for “heaven” is shamayim, which the Jewish people used as a circumlocution (substitute) for the name of God. So, the Kingdom of Heaven is also a reference to the Kingdom of God—they are the same.
