What is the kingdom of God?
Basic Christian doctrine teaches that the “kingdom of God” is not of this world, it is still future when Jesus returns, it is a kingdom where God rules.
But, to a student of Botany and Zoology, one is taught about the plant kingdom and animal kingdom. Consider therefore that when God created living things, he created angelic-kingdom, plant-kingdom, and animal-kingdom.
But, when it came to “man”, he started in Genesis with “an image of him and after his likeness”(Gen. 1:26). Adam was composed of matter (dust) and “breath of life”(spirit of man) and was created perfectly but “weak”(Matt. 26:40-43). There was a missing component that man needed that Jesus had to die and go back to the Father to get this gift to in-dwell in us (John 16:7;14:16-26). The Holy Spirit is key to finishing the work the Potter has planned for man (Jer. 18:1-6).
God was not creating a “human kingdom” or merely after an “image/ likeness” of him, not just “dust of the ground” (body). In fact, the dust-body will rot and we will be given another but “immortal body”.
Instead, God was creating a kingdom composed of “spirit beings like him”, a “Kingdom of God” above angelic kingdom. The kingdom of God is more than just a “government of God” and a place. It is a “new creation” (II Cor. 5:16-17) composed of immortal spirit-beings higher than angelic beings (Heb. 2:5) and unique to one another, yet “one” with the Son and the Father, all in the “God-Kingdom”, with the Father above all and the Son, our Elder Brother (For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren” (Heb 2:11).
