When our Creator told Pilate His Kingdom was not an earthly kingdom (John 18 v 36); Pilate was more concerned with the idea of Jesus being a king than in inquiring further regarding the nature of His Kingdom. Paul, in 1 Cor 15 v 44, tells those believers who were asking concerning the resurrected body that a spiritual body is given those receiving eternal life. These facts show that a physical earthly kingdom in which our Creator will reign on earth for a literal 1000 years is not what is being described by John in Rev. 20. It is rather describing a spiritual Kingdom where our Creator has been seated at the right hand of our Father and will continue in His reign until every enemy is brought under His power (1Cor. 15 v 24-26).
