In the synoptic Gospels , Mark and Luke use the Greek term " Basileia tou Theou ", commonly translated in English as "Kingdom of God."
--> Reich Gottes
--> Kingdom of Heaven
44 "In the time of those kings, the God of heaven will set up a kingdom that will never be destroyed, nor will it be left to another people. It will crush all those kingdoms and bring them to an end, but it will itself endure forever.
Luke 17:20-21 The Coming of the Kingdom 20Being asked by the Pharisees( A ) when the kingdom of God would come, he answered them, "The kingdom of God( B ) is not coming with signs to be observed, 21nor( C ) will they say, 'Look, here it is!' or 'There!' for behold, the kingdom of God is in the midst of you."[ a ]
Gottes Reich eine Welt, in der Gottes Wille geschieht, der alles Böse überwunden und alle Schuld vergeben hat, so dass Leid, Schmerz und Tod ein Ende haben. Nicht erst im Jenseits, sondern bereits hier auf Erden soll dieses Reich Gestalt annehmen. Für Christen sind Wirken, Tod und Auferstehung Jesu Christi der entscheidende Anfang zu diesem Reich.
C. H. Dodd and John Dominic Crossan argued that the “Kingdom” was fully manifest in the present teaching and actions of Jesus. Through his words and deeds the "Kingdom" was brought into the present reality of Palestine. Dodd coined the term " realized eschatology "  and largely based his argument on Luke 11:20 , and Luke 17:21 , claiming that "the kingdom of God has come to you" and “the kingdom of God is within you”. Crossan imagined Jesus as a cynic-like peasant who focused on the sapiential aspects of the "Kingdom" and not on any apocalyptic conceptions. 
Albert Schweitzer , Rudolf Bultmann , Norman Perrin and Johannes Weiss argued that Jesus’ "Kingdom" was intended to be a wholly futuristic kingdom. These scholars looked to the apocalyptic traditions of various Jewish groups existing at the time of Jesus as the basis of their study. 
In this view, Jesus was an apocalyptic preacher who would bring about the end times and when he did not see the end of the cosmic order coming Jesus embraced death as a tool in which to provoke God into action. The most common view of the "Kingdom" in recent scholarship is to embrace the truths of both these parties─present reality and future manifestation. Some scholars who take this view are N.T. Wright and G.R. Beasley-Murray. In their views, the “Kingdom” that Jesus spoke of will be fully realized in the future but it is also in a process of “in-breaking” into the present.
