1 Corinthians 15:42-44 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption: 43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power: 44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body
Actually 1 Corinthians 15:44 talks of no such thing. Paul is describing the process of resurrection to eternal life. There is a "natural body" which dies and is buried - sown like a seed into the ground. There is a "spiritual body" given at the resurrection (not immediately at death). He goes on to cite the example of Christ and his experience before and after his resurrection.
