Book excerpt: Here’s the Companion Study Guide for Psalmwriter Book II in the Chronicles of David. Wait Training draws parallels between weight training and the purpose of waiting in our own lives. Just as we build healthy bodies by watching our diet, practicing aerobic exercise and disciplined strength training so God uses the virtue of waiting to develop our spiritual, mental and emotional health. David’s wait of nearly fourteen years for his rewards is a guidebook for the Christian who faces the daily struggles of life and finds that waiting is an integral part of existence here on earth.
