Paul wrote, "Be anxious for nothing" (Phil. 4:6). Yet we seem to be anxious for everything. In fact, stress-related anxiety is so much a part of our lives that, somehow, it has escaped being identified as being sinful. We medicate it, but do not change the habits of fear that caused it in the first place. But anxiety is sin. At its core, it is a stubborn refusal to trust the goodness of God and rest in His sovereignty. Anxiety is a by-product of unbelief. It is a spiritual "terror attack" from hell that is silently killing tens of thousands every day.
