It was 100 years ago this month that a revival in Wales emptied the bars, brothels and courts, and filled the churches.

"During that revival, 100,000 souls were converted to Christ over a five-month span," writes Nancy Leigh DeMoss, author of a new release from Moody Publishers, entitled "Seeking Him."

DeMoss recounts how the turn of the twentieth century was marked by an unusual concern for spiritual matters. Believers throughout the world were moved to pray for revival.

"'Bend the church, and save the world!' was the cry that rang out through villages and towns, in the churches, and in the hearts of men, women, children and young people throughout the Principality of Wales," DeMoss writes. She highlights the story of Evan Roberts, a 26-year-old coalminer with little formal education who delivered a "Four Points" message to encourage an outpouring of the Spirit among the people:

1. Confess all known sin.
2. Put away all doubtful things and forgive everyone.
3. Obey the promptings of the Holy Spirit.
4. Publicly confess Christ as your Savior.

The revival that began in Wales spread to other countries including the United States. On Jan. 20, 1905, the headline on the front page of the Denver Post read: "Entire City Pauses for Prayer Even at the High Tide of Business." Portland, Ore., department stores closed for prayer from 11 a.m. to 2 p.m. each day.

"Few people today have ever witnessed revival and spiritual awakening on such a magnificent scale," DeMoss writes. But she believes "there is a growing sense of longing and desperation among many believers to see God ‘do it again!'"

DeMoss believes the time is ripe for another revival. Not only is her book set to coincide with the bicentennial of the Welsh Revival, but she hopes it will instigate renewed faith in the individual hearts of Christians in churches across the United States.

"I have longed to see such a supernatural work of God in our day," DeMoss writes. "Our world is under intense pressure — the mounting threat of terrorism, militant Islamism, rampant pornography, attempts to legitimize and promote homosexuality and same-sex marriage Ã¢â‚¬â€ these can leave Christians feeling helpless and overwhelmed by the flood of evil." But she said the ultimate solution lies "in the house of God and the hearts of his people."

Her work for the past 25 years has been with Life Action Ministries, a group that has conducted more than 1,200 extended revival meetings in local churches. "Seeking Him" is a compilation of materials the group has used in 12-week studies aimed at reviving Christians individually and corporately.

"This is something that Life Action has used in churches for 25 years," said Rhonda Elstrand, advertising manager for Moody. "But they've never had it in book form."

DeMoss thanks the publisher in the foreword of the newly released title for moving forward with a project that had been forgotten.

"In our churches, we have tried everything that money can buy — sophisticated strategies, cutting-edge technology, media blitzes, big-name artists and speakers, jam-packed stadium events … but our souls are still empty and our witness in the world is anemic at best," DeMoss said. "As the Old Testament prophet said, ‘It is time to seek the Lord' (Hosea 10:12). He is our only hope!"

DeMoss is the host and teacher for Revive Our Hearts, a nationally syndicated radio program for women heard each weekday on approximately 500 stations. She will launch a 12-week series on the program to accompany the book's official publication.

DeMoss is praying that God will use the book and the radio series "as an instrument of revival in thousands of hearts, homes and churches Ã¢â‚¬â€ for his glory."

"This workbook is not intended to add more ‘shoulds' to your life," DeMoss writes. "Rather, its purpose is to reveal more of God and his ways to you, to gently expose your heart, and to lead you on a pilgrimage toward greater freedom, forgiveness, fullness and spiritual fruitfulness."

In addition to "Seeking Him," DeMoss has written "A Place of Quiet Rest," "Lies Women Believe" and several other books. They have collectively sold more than 360,000 copies.

She said she wants her latest book to speak to anyone who feels overloaded and worn out, or to Christians who feel they are only "going through the motions" of their faith or "running on empty."

"The God who displayed his glory in the great awakenings of the past is the same God we worship today," DeMoss writes. "He has not changed. He is no less able to turn the heart of a nation today than he was 100 years ago!"
