The line dividing good and evil cuts through the heart of every human being. (Aleksandr Solzhenitsyn, late Soviet dissident and novelist)
It’s an idea that many people want to refute or ignore. We really don’t want to think that anything evil could ever be in our hearts and mind. Yet, to be honest, we all have to admit that we do sometimes have evil thoughts or may be tempted to do wrong. It is a matter of the heart, isn’t it? And we would do well to examine ourselves to be sure our thoughts and motives are pure.
Everything is pure to those whose hearts are pure. But nothing is pure to those who are corrupt and unbelieving (Titus 1:15).
