Too many people today do not believe that the devil, from Genesis 3, also called the “ancient serpent” in Revelations 12:9 still moves in the earth today. All the evil that happens in the world today is because of Satan. Scammers constantly trying to figure out new ways to rob people. You have to be very careful who you allow to keep or have unmonitored access to children, because people might do some awful things with them. People just want to kill other people just because they can. Nations wanting to take over other nations. Other nations wanting to restore old empires.
Many More Evils
There are many more evils, that is to say sins that I could mention, but I will not. Just know that as sure as you may believe in God, you should believe in the devil, Satan that God cast of heaven with the angels that support him, (see Revelation 12:9).
