Are there 2 kingdoms because the Bible says that there is a kingdom, yet the Bible also says that the church is kingdom?
Paul said, “And the Lord shall deliver me from every evil work, and will preserve me unto his heavenly kingdom: to whom be glory for ever and ever.” (2 Tim. 4:18) Likewise Peter said, “For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.” (2 Pet. 1:11) So what is the kingdom? Well, we know that Christ is the King over the kingdom. (Col. 1:18) Second, the scriptures tell us that the church is the kingdom. (Matt. 16:18ff), but are there 2 different kingdoms? This answer is no. Christians (ones added to the church by the Lord) have been translated meaning that they are citizens in the kingdom. (Col. 1:13, 14) The kingdom on earth is not a physical kingdom, but a spiritual one and when faithful Christians die, they will go to Abraham’s bosom and be reunited with the brethren there. Likewise when the world is destroyed, the kingdom will be collected from those living on earth at the time and those in Abraham’s bosom to be delivered to the Father and all be given entrance into Heaven which is the heavenly country where God has prepared the kingdom a city to dwell in. (Heb. 11:16) Now, we know that only the faithful will be there (Rev. 2:10). And, we know that the kingdom is a spiritual place where flesh and blood cannot dwell. (Rom. 8:1-16) This is why no man will every destroy the kingdom neither can it be moved because once the church was established, it will continue on for all eternity. (Dan. 2:44) Robert Notgrass
