There are key differences between a glorified body and an Adamic body. Although both may look similar, their construct is different. A human is a triune being, made up of body, spirit, and soul. This is how Adam was in the Garden of Eden, except that he had eternal life, and could never get sick, or experience any negative emotion. His body had a glory to it, but it was not a glorified body.
In the eternal kingdom, the nations of the saved will have Adamic bodies, or the same type of body that Adam had before the curse of sin came upon it. The Adamic body is of flesh and blood, whereas the glorified body, whilst also triune in its makeup, is of flesh and bone, having no blood.
Jesus had a glorified body after His resurrection. It was a body that could change form (Mark 16:12), appear and vanish (Luke 24:31,36), it could eat and drink (Luke 24:30; John 21:12-13), and yet looked so normal that it could pass unnoticed.
The glorified body is the product of the celestial (heavenly) body blending itself into the terrestrial (flesh) body. This blending of the celestial with the terrestrial means that the glorified body has the capability to contact the supernatural world and the natural world, and can move between worlds; whereas those in Adamic bodies will be locked into this world.
The glorified body is also triune in construct, except that it is not a body of flesh and blood (as the Adamic body is), but is a body of flesh and bone (Luke 24:39). In a body of flesh and blood, the bloodstream is the carrier of the spirit of natural life (Leviticus 17:11). But for a glorified body, it will not have any blood in it; instead, it will pulsate entirely by the Holy Spirit. The prophet of God explains this for us in the message Letting off the pressure (January 13, 1963).
The Adamic body is triune as a body, spirit, and soul, and the glorified body is triune as a flesh body, celestial body, and soul. Thus, for the glorified body, the natural spirit of life will have been replaced by the celestial body that pulsates by the Spirit of God.
Paul says in 1 Corinthians 15:50: Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption. A body of flesh and blood will not be heir to the Kingdom of God. That is why only the redeemed have an angel, or celestial body, already in Heaven (Matthew 18:10; John 14:2; 2 Corinthians 5:1-2). The new birth was given to make a way for the redeemed to enter their new (or glorified) body at the translation (or Rapture) of the saints, so that they can rule and reign with Christ.
The nations of the saved never had a celestial body, or heavenly representation, in Heaven, but they are given eternal life at the Great White Throne of Judgment. Their bodies and position in the eternal kingdom will therefore be of a lesser status than the bodies and position of the redeemed of God.
Those in an Adamic body shall enjoy eternal life, remaining always in the bloom of youth, free from sickness, and every negative emotion. The redeemed in their glorified bodies shall also enjoy these things, but they shall also have the creative power of the Spoken Word, they shall travel at the speed of thought, they can transcend dimensions, and so much more.
Unlike Adam and Eve, whose bodies were designed to fall and reproduce offspring by sex, the Adamic body and the glorified body will not have any reproductive organs. Men and women will still have the form and visage of male and female, but the need to reproduce will be gone, because all whom God foresaw as being in the eternal kingdom will be there.
