Every year, millions of dollars and countless hours are spent in a futile search for spiritual peace and security. For many Christians, this effort is often motivated by a lack of peace in their earthly lives and a persistent insecurity with regard to their afterlife. They attend self-help seminars, which claim to provide the answers for peace in their daily lives. They search the scripture, attend church and Bible studies, and often adhere to strict doctrinal beliefs that purport to lead one to salvation. Yet so many are still filled with anxiety and doubt. However, when John the Revelator looked to the end of time through God's prophetic lens, he saw a multitude no man could count - of all nations, tribes, peoples, and tongues - all rejoicing in their salvation. How could all these people, representing every part of the world through the millennia of time, have access to the knowledge of salvation? Certainly our traditional view of how the gospel is spread could not possibly account for such diversity of peoples, geography, and ages. Just as clearly, this knowledge was not obtained through any modern invention such as the self-help movement. So, how did this multitude obtain peace and salvation? The answer is simple: "There is a spirit in man, and the breath of the Almighty gives him understanding" (Job 32:8). The Spirit Within explores this mystical statement and finds within it the secrets to peace, a spirit-filled life, and God's saving power.
