Yet death still had power over all who lived from the time of Adam to the time of Moses. This happened, though not everyone disobeyed a direct command from God, as Adam did. In some ways Adam is like Christ who came later.
Even though the Law of Moses says that the priests must be descendants of Levi, those priests cannot make anyone perfect. So there needs to be a priest like Melchizedek, rather than one from the priestly family of Aaron.
This is why Christ did not go into a tent that had been made by humans and was only a copy of the real one. Instead, he went into heaven and is now there with God to help us.
Those flood waters were like baptism that now saves you. But baptism is more than just washing your body. It means turning to God with a clear conscience, because Jesus Christ was raised from death.
