Why? Perhaps because there was no freedom of expression and people were stoned, imprisoned, enslaved, maimed, and killed for trivial reasons every day. The fact is that he did.
The kingdom of Heaven is like hidden treasure lying buried in a field. The man who found it (Jesus H. Christ) buried it again.....
There is a reason the Kingdom cannot be found here on earth. The kingdom is not of this world........it rests within the Spirit of those who would follow God, Its a spiritual kingdom, that resides within the heart of those who obey the laws of the kingdom (Luke 17:20-21).
Those who can't find the kingdom are looking in the wrong places........this world. Its all about the eternal salvation of the Spirit that is made in the image of God, its never been about the flesh.....we are to feed the spirit in truth, not the flesh and things that were created to decay and fade back into the dust from which they came. Jesus chastised the 5000 He had just feed with the fish and the loaves for not comprehending the difference. -- John 6:26-27
Jesus was the promised King, but His kingdom was not of this world. (John 18:33-37). The Messiah was promised to rule over David's Kingdom (Isa.9:6-7), Jesus was made both Lord and Christ of the kingdom (Acts 2:36) Jesus used the present tense when speaking about the Kingdom, the Kingdom would arrive with power in the lifetime of those listening to Jesus teach (Mark 9:1)
The church and kingdom are used in a synonymous manner, Jesus refers to the church and the kingdom being one and the same in Matthew 16:18-19. But there is a literal difference between the 2. Church translated from the original Greek, "ekklesia" which means "the called out". Called out from what? The world (John 18:15-27). Those who are part of the Church that Christ was given by the Father are called out from the world and into the kingdom of light. Church therefore refers to the WHO. Kingdom refers to the Where, to where are the Church members called out? A place governed by the laws established by the Words of Jesus. (John 12:48)
The church of Christ Jesus did not exist until people were called out from the world to enter the kingdom of God/Heaven/Jesus Christ (Col.1:13-14).....all are synonymously used. Church, Kingdom of Heaven, Kingdom of God, Kingdom of Christ.
Daniel stated that the Messiah, Jesus, would receive a kingdom (Daniel 7:13-14)......not found it, but it was given to Him by the Father along with ALL AUTHORITY IN HEAVEN AND IN EARTH (Matthew 28:18-20)....those who are conveyed into the Kingdom (Col.1:13).......are conveyed by being baptized in the Name of the Father, The Son and the Holy Ghost, you are baptized INTO CHRIST JESUS (Romans 6:3-7, Gal.3:27-29), then you become joints heirs of the promises made to father Abraham. Within this kingdom there is neither Jew nor Greek, Bond or Free, Male or Female.......all are equal in the eyes of God.
