People tend to fear things they don’t understand. Fear is arguably the root of all negative emotions and actions; it causes hatred, jealousy, anger, and all the rest.

Also, this is a reference to Jesus' resurrection; the ‘darkness’ of death could not overpower the ‘light’ of Jesus.

The poor in spirit means those that are humble. Not necessarily monetarily, though if you have been poor it is easier to have the spirit. It is an important distinction here between material needs and spiritual needs.

Matthew 19:24 says:
