A threat that's hard to assess is a fear that's hard to keep away. The fear of the unknown is a primeval instinct of humanity. Such fears have been played upon in years past by documentaries and movies about biological warfare. The fact that some such tactic seems to have been employed by terrorists, and that some people have actually died from anthrax infection, means that there is a new cloud of unease hanging over American heads.
Of course, the likelihood of contracting anthrax is negligible, especially compared to other risks that we daily run. But that this risk, unlikely as it may be, is delivered by way of the mail and whose victims seem so random brings all within its scope of fear. The visit of the mailman certainly has a new dynamic to it these days in America. Few things could have been better calculated to unsettle the ordinary citizen than a deadly infection spread by the mail that in its early signs of contagion is practically indistinguishable from the 'flu.
Uncertain times
What is the Christian to do in such uncertain times? The Bible is uncompromising in its remedy for groundless fears: 'Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and minds in Christ Jesus' (Philippians 4.6-7). Clearly there is a godly concern - Paul was concerned for the churches - and a reasonable concern - we are called to provide for our families - but all concerns need not for the Christian become neuroses, 'anxiety'.
