The church is extremely important for believers, providing a place for mutual support, prayer, and the collective pursuit of fulfilling the Great Commission. This is what the Lord desires. However, new believers who join the church may drift away if they lack proper guidance or systematic teaching, leading to a lack of understanding of the truth even after years of faith. Conversely, believers who receive proper guidance can become valuable workers and preachers in the church. Therefore, effective discipleship training and the development of small groups are crucial. This specialized course covers topics such as discipleship training, the establishment and leadership of small groups, and training for group leaders and mentors. It aims to help brothers and sisters build the church together, shepherd the flock, and spread the Lord’s name more effectively.
