Why does Satan attack our bodies and how does Satan attack our bodies?

Satan attacks our minds with lies and we can fight back with God's truth.

Jesus takes care of an unclean spirit, because He has authority and gives us spiritual authority

The war we're in happens to everyone, it is in two realms, it is between two kingdoms, it is won by Jesus, and it can be fought with weapons God gives us. 

Sabbath is a gift from God; Jesus is the author and fulfillment of Sabbath; Jesus is the source of Sabbath restoration and new creation.
