Many people in the world, today, do not believe in the resurrection of the dead. Their belief is like the Jewish sect of the Sadducees, of old. We read about their lack of belief in Acts chapter 23 verse 8a. However, there is a mighty resurrection that will take place for all. The spirit or real person of a Christian, who has died, physically, has already been resurrected. Spiritually, all true Christians, were resurrected when Christ arose from the dead and they are already seated with Him, at the right hand of God the Father. For those Christians who are alive, at this moment, on earth, this will be a future event but their spirit person has already been resurrected when they repented of their sins and made Jesus Christ, the Son of God, the Lord and Saviour of their life.
