I've been thinking about this lately and came to the conclusion that good always wins over evil. I believe that good reflects light and evil darkness. Every day we are met with a sunrise which represents good and the sun set and on coming of evening and darkness is a representation of evil. Even when darkness takes over, we still have light from the moon and stars. As long as someone is willing to shine their light in the darkness, they will always win over evil.
I will admit that doing evil is easier than doing good. The best way I could explain it is if you can imagine that you are in a canoe trying to go up river against the current. My ex-brother in law and I canoed on a lake and the wind changed and it was nearly impossible for us to get back to shore. We did eventually but it took all of our efforts. Sometimes the struggle between good and evil is very difficult but it is worth it. For some reason our brains are wired to seek evil. Just think, when you eat food, why is it that the foods that you like most are bad for you or why is it that alcohol and drugs which destroys your body feels yet feels so good to your brain. It's almost like our brains are hard wired to enjoy evil and self destruction. I think if we are able to override your genetic impulses there is hope. We need to search good and reject evil as much as possible. I hope this makes sense, I understand myself but others might not
