Shalom! Welcome to Catatan Josephine. The silent killer is the spirit of bitterness. This is what I called it. It's also because this is what I saw every where, mostly everytime in our society and inside our culture right now. This is like a two-edge sword killing your soul & flesh. It seems harmless but it's dangerous. People who have this spirit sometimes doesn't know that they have it. It caused death. People who have this will have constant pain both physically and mentally. Emotionally disturbed. Death are lurking at the end of the tunnel that they are not be able to see it because their heart are blinded. The symptoms usually appear since a person at very young age. We are be able to recognize it. Be aware of this, and back to Jesus's love.
