The Holy Ghost throughout the Old Testament, empowered certain people to do amazing things physically that resulted in violence and death: David, Gideon, and Samson are examples of this. But the truth is, this same kind of deadly Ghost power is still available to us today, but for a different purpose. Not to kill our enemies, but our sin!
