Don't let the devil steal your joy. That's one of the cornerstones of Joyce Meyer's teachings. I know some people get weirded out when the devil is referred to, because it seems so hard-core. But I've come to realize that if we acknowledge his presence, we become aware of him and thus become better able to fight and suppress him and his works.
I wanted to remind myself of everything that makes me happy so I created my own lists events, occasions, people and memories in my life because through this i can see how truly blessed I am.
