The new groups initiative is a partnership between churches, state conventions and LifeWay.
It's designed to help longtime churchgoers jumpstart their faith and to help new believers grow spiritually, Bruce Raley, director of church education ministry for LifeWay, said.
Whether they meet on Sunday mornings or during the week, small groups are the best way to learn the habits of faith, such as prayer, Bible study and serving others, Raley said.
"Discipleship takes place best in the context of a relationship," he said. "And relationships are most likely to develop in a small group."
So far, about 17,000 new groups have been registered at GroupsMatter.com, which includes guides for starting new groups, resources for new leaders, and promotional materials.
Raley and other organizers say the new groups can be started at any point in the year. But they suggest the first Sunday in September as one of the best options. That way, he said, churches can spend the summer months getting ready.
"We believe thousands of new groups will kick off on that day," he said.
The idea of starting 100,000 new groups began as a grassroots effort.
About three years ago, Bob Mayfield, a small groups expert at the Baptist General Convention of Oklahoma, and some other state small groups leaders were having breakfast at a denominational meeting and talking about ways to draw more people into groups.
"We needed something dynamic -- something our people could grab hold of," he said.
Not long afterwards, Mayfield and the others met with Raley, who brought up the idea of starting 100,000 new groups, as part of the Groups Matter campaign. It was just what they needed to hear, Mayfield said.
"This is something people have been waiting to do," he said. "But nobody had said, 'This is what we are going to do.'"
The new initiative piggybacks on existing small group ministries that most churches already provide, Mayfield said.
"It's the one strategy virtually all of our churches have -- either they call it Sunday School, life groups or community groups," he said. "It's already the largest organization in most churches."
And small groups are often their most effective discipleship program. Small group members read the Bible more, give more and are usually more spiritually mature.
A study of 3,500 Protestant churchgoers in North America from LifeWay Research found that those who belong to a Bible study group are more likely to go to church at least four times a month (79 percent) and to read the Bible daily (28 percent). Being in a group helps them feel closer to God (69 percent) and understand the Bible better (74 percent), and become more loving in their relationships (47 percent).
Group members also develop deep friendships, often staying together for years.
The LifeWay Research study, which was published in a new book called "Transformational Groups," found that half of current group attendees have been in the same group for at least two years. A quarter (27 percent) have been in the same group for more than five years. But having tight knit groups has a downside, Raley said. It's often hard for new people to join.
"The reality is that many groups close after a few years," he said. "Relationships in a group go from being social to being personal. That's good for the group but bad for people trying to get in the door."
Launching new groups means more space for new people, Raley said.
Mayfield agrees. A good small group will form a tight social circle, he said. That's hard for newcomers to break into.
"But in a new group, the social circle is wide open," Mayfield said.
That was the case for Tommy "TJ" Thresher of First Baptist Church in Moore, Okla. Being part of a small group has been crucial in helping him learn the Christian faith, he said.
Thresher, a sergeant in the Oklahoma National Guard, didn't grow up in a church-going family, and had little interest in faith. In the summer of 2012, he said his wife decided to give church a try.
"She woke up one day and said, 'I'm going to church. You can go if you want to,'" he said.
Thresher did, and said he was hooked from the first Sunday. A few weeks later, he gave his life to Christ. That fall, he decided to help start a small group -- which his church refers to as a "life group" -- on Sunday mornings, with other newcomers to the church.
"The best way for a follower of Christ to learn is to really get in there with believers," he said.
Churches will find a welcome audience for new groups, according to LifeWay Research. The LifeWay small groups study found that many churchgoers who aren't part of a group are open to joining one.
Among the types of changes in life situation that lead to no longer attending are family responsibilities (26 percent), general busyness (26 percent) or work responsibilities (25 percent) kept them from attending.
About a third (33 percent) said they are busy when groups are offered at the church. One in five (22 percent) said groups are offered at an inconvenient time.
Churches should offer groups at a variety of times and in a number of settings to attract as many people as possible, Raley says.
Cross Point Church in Nashville has already started 140 new groups this year as part of the new groups initiative. Most of those groups meet in homes. But they hold the first meeting at a church campus.
Chris Surrat, Cross Point's missions pastor, says that approach makes it easier for new members to plug in.
"We have all the hosts and leaders in a room, at tables, and we walk people through the first week," he said. "We tell them, this is what it will be like for the next five weeks. It's less scary to experience small groups at a church for the first time."
Thresher said being in a small group has changed his life. It's helped him grow as a disciple.
"Without a life group, I think my faith would have become stagnant by now," he said.
