The "Workers-in-Training" manual for the Redeemed Christian Church of God (RCCG) is a comprehensive guide designed to equip believers for effective service within the church. This manual provides detailed instructions and guidelines to ensure that church workers are spiritually prepared, committed, and qualified for their roles. The following is an in-depth summary of the manual's contents:

Preface
The preface emphasizes the eternal significance of committing to God and securing one's salvation. It underscores the necessity for spiritual effort to integrate new believers into the church fellowship and mobilize them for soul-winning activities. The Workers-in-Training program aims to prepare believers for ministry, ensuring they are spiritually fruitful.

Introduction
The introduction outlines the divine origin of the RCCG, named through a revelation to its founder, the Late Rev. J.O. Akindayomi. The church is depicted as having specific divine promises, including being a model church and experiencing rapid global expansion. This divine backing necessitates clear qualifications and conduct for church workers.

Brief History of RCCG
The RCCG was founded by Reverend Josiah Olufemi Akindayomi, who received the church's name through a divine vision. Born in 1909, Akindayomi left the C&S Church to start what eventually became the RCCG. Since 1981, under Pastor Enoch Adejare Adeboye's leadership, the church has grown significantly and is now present in over 200 countries.

Vision/Mission Statement
The RCCG's vision includes:
1. Making Heaven.
2. Taking as many people as possible with them.
3. Having a member of the RCCG in every family worldwide.
4. Adopting holiness as a lifestyle.
5. Planting churches within close proximity in all nations.

The RCCG is committed to pursuing these objectives until the world is reached for Jesus Christ.

Qualifications of a Worker
Workers must meet several spiritual criteria:
- Be born again, sanctified, and filled with the Holy Spirit.
- Baptized by immersion.
- Tithe-payers and cheerful givers.
- Proven soul-winners, humble, prayer warriors, well-behaved, given to fasting, trustworthy, and blameless.
- Meet any additional criteria set by the Mission.

Discipline Among Workers
Discipline is crucial for maintaining order and spiritual integrity. Workers who sin or violate church principles face disciplinary actions, such as open rebuke, suspension, or dismissal. Genuine repentance can lead to pardon and reinstatement, while lack of repentance may result in prolonged suspension or dismissal.

Promotion Among Workers
Newcomers progress through stages from non-baptized members to baptized members, workers in training, and fully-fledged workers. Promotions to higher positions like Deacons, Assistant Pastors, and Pastors require exceptional character, spiritual endowment, and participation in church training programs.

Additional Modules
The manual may also cover topics like spiritual appointments, divine endowment (gifts, calling, and ministry), the ministry of reconciliation, brokenness in Christian service, and church administration. These modules provide further guidance on effective service within the RCCG.

Conclusion
The manual concludes by encouraging believers to fully commit to their roles and responsibilities within the RCCG, emphasizing that their service is ultimately unto God. It aims to prepare workers who are spiritually mature, dedicated, and ready to contribute to the church's mission of spreading the Gospel and making disciples worldwide.
This manual is a crucial resource for ensuring that church workers are well-equipped to support the RCCG's vision and mission, fostering a spiritually vibrant and effective church community.
