Isaac was born after the Spirit, yet he was as real and literal a child as Ishmael was. So the true seed of Abraham are only those who are spiritual, but that does not make them any the less real. God is Spirit, yet He is a real God. Christ had a spiritual body after His resurrection, yet He was a real, literal being, and could be handled the same as other bodies. So the bodies of the saints after the resurrection will be spiritual, yet they will be real. Spiritual things are not imaginary things. Indeed, that which is spiritual is more real than that which is fleshly, because only that which is spiritual will endure for ever. EVCO 76.3
