Mary's assumption is hope for our victory over sin and death.
1. The assumption and many of Mary's life were not recorded in scripture.
2. She lived 15 more years after her son's ascension to heaven to help the apostles establish the Church.
3. She could have not died because she was free from original sin but she chose to die to follow the footsteps of her son.
“To share in Christ’s Resurrection, Mary had first to share in his death.” - Pope John Paul II
