Henrietta lectured and wrote passionately about Sunday school's power to teach others the Bible. Within two years, Sunday School attendance at Hollywood “Pres” was averaging more than 4,200 per week. She served in leading the Sunday School program from 400 to 6500. Henrietta Mears taught the college age program herself. Henrietta Mears was one of the most influential Christian leaders of the 20th Century. She founded Gospel Light, a publishing company for many of her training materials, Forest Home, a Christian conference center nestled in Forest Falls, California, and "Gospel Literature Internationals (GLINT)"., and profoundly impacted the ministries of Bill Bright and Vonette Zachary Bright (Campus Crusade), Jim Rayburn (Young Life) and Billy Graham (Billy Graham Evangelistic Association) and Louis Evans, Jr. who was the organizing pastor of Bel Air Church (where Ronald Reagan and many other stars attended) and led the congregation of the National Presbyterian Church, Washington, D.C., with her emphasis on Scripture and a clear Gospel message for young people.
