1 Corinthians 15:21

For since by man came death, by man came also the resurrection of the dead (KJV)

Then: The Corinthians were ready for the explanation. By man, the actions of Adam and Eve, came the first physicial death. By man, the actions of Christ in living a life without any kind of sin, came resurrection to spiritual life, and the death of death. The Corinthians still lived when the concept was new, they could talk to people who had seen the risen Lord. They could know themselves through the Holy Spirit. Christ led the way so all could be forgiven and resurrected.

Now: We keep on reading the original testimony. We keep on passing the information down generation to generation. We keep on being given the gifts of the Spirit. So like the Corinthians, we are forgiven and look forward to resurrection. We shall have a part in the favor of the first fruit (Henry).
