We have been called by God for the salvation of our souls, in order to live a life surrendered in worship of God; but also to have a productive life in all aspects. The child of God has been rescued from the world, transformed by God, and enabled to serve Christ, his church, and others. The Christian must dedicate his entire life to service. Therefore, serving must be one of the most beautiful obligations that the believer can develop in this world. When the child of God serves the Lord and other people, he can find purpose in his life and live with a satisfaction that lasts forever.

Many Christians are consumers and not reproducers, that is, they continually need to be carried and supported since they have not grown enough to support themselves. So, we must ask ourselves, why does this happen? Why are many people in the local church inactive? Why do many Christians not know what to do with their lives? This book has been written with the purpose of helping the child of God know why he is here on earth, and how he can live a productive life in Christ. The objective of this book is to prepare and train children of God who have recently been baptized and who want to serve God, but do not know how or where to do so. Additionally, it tries to fill the need of those pastors who have new people who want to serve God. Therefore, this book can serve as material for the preparation of male and female servants for the work of God. Finally, the child of God will learn that his calling will be realized by serving in a local Church ministry.
