There is a widespread belief that ‘balance’ means mixing a little bad in with the good. There are religions, philosophies, and even doctrines taught in some Christian circles that teach everything good is balanced by something evil. Light is balanced by dark, yin-yang, and so forth.
According to the Bible, God created everything, and everything He created was Good. Evil was introduced later through the rebellion of satan and man. Evil is not an agent of balance, but a disease, a blemish, an abberation, an agent of rebellion.
God intended that Love provide the balance and bridge between His goodness and our badness.
