"Kingdom Of God is at Hand" - Which Kingdom was Jesus and John the Baptist talking about? The Bible clearly says that Jesus preached that the Kingdom of Heaven was at hand. 


  Matthew 4:17: From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand. 



What kingdom was Jesus preaching about?
Has this kingdom been established?
Romans 14:17 tells us that the kingdom of God is righteousness,peace and joy in the Holy Ghost.  Personally, I think it is a state of mind.   The Bible also says that it is a mystery (Mark 4:11). However it also tells us how to get into the kingdom of God now.  First one must seek for it. Secondly, John 3:3 and verse 5 it tells us we must be baptized in water and also in the Holy Ghost or Spirit "to enter into the kingdom of God."
