The doctrine of Resurrection is diversely understood today. Is it going to be physical or non-physical? What is a spiritual body? This book digs into the depth of the Word of God, delving into the overall point of the human race from before the time of Adam, how it's not abandoned since the fall of Adam, and when and why the resurrection will take place. Apostle Paul asked the question that was immediately followed by the core distinction that separates truth from error concerning this subject:

1 Corinthians 15:35-36 But some man will say, How are the dead raised up? and with what body do they come? (36) Thou fool, that which thou sowest is not quickened, except it die:

The element of our beings that shall resurrect is an element that lives, then dies, and then is intended to come alive a second time. Seeing as a man is comprised of a spirit, soul, and body (1 Thess. 5:18), it can only be the body that lives as we serve God as believers in this mortal flesh, then dies, and is made to live again at the resurrection. See how neither the soul nor spirit of a believer fits this criterion that Paul laid out for the part of us that is resurrected in our future, and see its purpose for the eternal place of God.
