Faith and anxiety are not absolutes. That is, if you experience one, you do not eliminate the other. Faith can keep company with many sets of ordinary feelings that can be handled and lived with but never removed. Those who insist on a "pure faith" unstained by human emotionality make the denial of reality a condition of faith. But the encouragement of the Scripture is to "take heart," not take cover. We take heart because we believe that human life in its totality becomes enormously fruitful in the hands of God through the power of God's gracious promises.
