What is the best illustration of what our resurrected body will be like?
The best illustration is the Lord Jesus during the 40 days after His resurrection. Believers will not be invisible spirit beings or angelic beings but will exist eternally in a body, not the same flesh and blood, yet on the same order.
Les explains that the resurrection body is not an invisible spirit or angelic existence. Instead, believers will be eternally existing in a body. It will not be the same flesh and blood body we now have, but it will be on the same order. The best illustration he gives is the Lord Jesus during the 40 days after His resurrection. Paul is the one who provides the real detailed explanation of resurrection, and Old Testament saints also believed in it—Job spoke of seeing God in his flesh, and David expected to go to his deceased child.
