Modern mysticism embraces a concept of faith that in effect rejects reality and rationality altogether. Waging war on reason and truth, it is thus in direct conflict with Christ and Scripture. It has taken hold rapidly because it promises what so many people are seeking: something more, something better, something richer, something easier – something fast and easy to substitute for a life of careful, disciplined obedience to the Word of Christ. And because so many lack certainty that their sufficiency is in Christ, mysticism has caught many Christians unaware. It has thus swept much of the church into a dangerous netherworld of confusion and false teaching.
