Kingdom of God / Kingdom of Heaven

There is a lot of misunderstanding about what the two phrases "Kingdom of Heaven" and "Kingdom of God" actually mean. A lot of good men have endeavored to explain these in high sounding, mystical terms, but if you look at the Scriptures it is easy to see how they refer to the same thing.  They are the same thing, which is the Millennial Kingdom that Christ will set up and rule the earth, with His throne at Jerusalem.

If you first look at 1 Chron. 28:5, David refers to his kingdom as "The Kingdom of the Lord" since God was the one who gave the throne to Him and established his rule. Also, in 2 Chron. 13:8, Abijah also calls David's kingdom as "The Kingdom of the Lord." This is the Kingdom, once removed, that is prophesied to one day be set up again with David's Son (Christ) ruling the world from David's throne in Jerusalem. This is the kingdom that was looked for by the pious Jews, and was declared as such by Gabriel when he visited Mary.

"And the angel said unto her, Fear not, Mary: for thou hast found favour with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end." (Luke 1:30-33)

When you look at the Gospels you will find that the Kingdom of Heaven and the Kingdom of God are interchangeable between the different Gospels, so they mean exactly the same thing. Compare Matt 5:3 and Luke 6:20,

"Blessed are the poor in spirit: for theirs is the kingdom of heaven." (Matt 5:3)

"And he lifted up his eyes on his disciples, and said, Blessed be ye poor: for yours is the kingdom of God." (Luke 6:20)

Also Matt. 13:11,
"He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given."
with Mark 4:11,
"And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables:"

"Kingdom of God" is designated Christ's Kingdom in Matt. 16:28, Luke 9:27, and Mark 9:1.

"The Father's Kingdom" and Christ's are the same - Matt. 13:41-43 with Eph. 5:5,

"The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear."

"For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God."

also Matt. 26:29 and 2 Pet 1:11.
"But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father’s kingdom."

"For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ."

The Kingdom is David's Kingdom restored, and that was what the Jews and the Disciples were looking for. Acts 1:6:

"When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?"

"And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power."

(which, if it wasn't the Davidic Kingdom Jesus would have corrected them here instead of saying the time for it's restoration was in the Father's hand), Matt. 20:21, Acts 15:16, Luke 1:32.

"And he said unto her, What wilt thou? She saith unto him, Grant that these my two sons may sit, the one on thy right hand, and the other on the left, in thy kingdom." Jesus would also have corrected John's mother if there were not thrones that the sons could possibly sit on. Such seats of honor, Christ told them, would come only with the highest price of suffering: "Are ye able to drink of the cup that I shall drink of, and to be baptized with the baptism that I am baptized with?" They would indeed drink of the cup of suffering as Christ did, but still those cherished seats would only be given to whom the Father deemed worthy of them.

"After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:"

"He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David:"

These verses describe a literal physical Kingdom, and this is what the Jews looked for and the disciples asked about in Acts 1:6. With this important key in mind, Scripture talking about the Kingdom (of God or of Heaven, etc.) open up an incredible door to the World to come when viewed in the meaning that the Jews understood.

This is the Kingdom for us to seek just as the Jews and the Apostles did, and that Jesus Christ commanded us to strive for.

"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you." (Matt. 6:33)
