The
Gospel of Luke records Jesus' description of the Kingdom of God, "The kingdom of God does not come with observation; neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you." In the
Synoptic Gospels, Jesus speaks frequently of God's kingdom. However within the
New Testament, nowhere does Jesus appear to clearly define the concept. Within the Synoptic Gospel accounts, the assumption appears to have been made that, "this was a concept so familiar that it did not require definition."
John's Gospel refers to the Kingdom of God in Jesus' dialogue with
Nicodemus in
chapter 3.
Constantin von Tischendorf's text is exceptional in referring to "the kingdom of heaven" in John 3:5, on evidence which
Heinrich Meyer describes as "ancient but yet inadequate". Within the non-canonical, yet contemporary
Gnostic Gospel of
Thomas, Jesus is quoted as saying, "If those who lead you say to you: ‘Look, the kingdom is in the sky!’ then the birds of the sky will precede you. If they say to you: ‘It is in the sea,’ then the fishes will precede you. Rather, the kingdom is inside of you and outside of you. When you come to know yourselves, then you will be known, and you will realize that you are the children of the living Father." This same Gospel of Thomas further describes Jesus as implying that the Kingdom of God is already present, saying, "The kingdom of the Father is spread out upon the earth, and people do not see it." The Kingdom of God (and its possibly equivalent form
Kingdom of Heaven in the Gospel of Matthew) is one of the key elements of the teachings of
Jesus in the
New Testament. Matthew is likely to have instead used the term
heaven because the background of his
Jewish audience imposed restrictions on the frequent use of the
name of God. However, Dr.
Chuck Missler asserts that Matthew intentionally differentiated between the kingdoms of God and Heaven: "Most commentators presume that these terms are synonymous. However, Matthew uses
Kingdom of Heaven 33 times, but also uses
Kingdom of God five times, even in adjacent verses, which indicates that these are not synonymous: he is using a more denotative term." Kingdom of God is translated to
Latin as
Regnum Dei and Kingdom of Heaven as
Regnum caelorum. ==Christianity==
