Evil in the world is constant, and it's in the same world where we live our lives and have our loved ones. As much as we love them, we cannot always be there to protect them and keep them safe. However, when we pray, God can.
When you are concerned about the safety of your family, say this prayer
Dear God, please keep my family safe anywhere they might be at any time. I pray that your banner over them is constant and that you arise to fend evil away from them. I pray that you keep them secure and that you bless and order their journey away from disaster and catastrophe. I pray that they are never left unguarded by your heavenly force. I pray that you walk with every member of my family in all their ways and keep the wicked ones away from them. When a catastrophe is ahead, please, Father, lead them away from it and always bring everyone home safely.
