The Christian life is wonderful, but we must learn to live it, and even more so; we must know that it has many ups and downs. Many people begin the Christian journey, but when struggles and trials, problems, and difficulties come, they abandon it because they didn't understand what they were going to encounter. On the other hand, they didn't learn the basics to face those situations and continue forward, persevering in the Lord. This book has been written to help Bible institute students understand the basics of the Christian life, but also as a tool for pastors and teachers who work in the formation of new believers. In it, the reader will learn details about the Christian life, its meaning, and the basic themes of the faith that will help them understand life in Christ. In addition, the student will learn about the need to grow spiritually, about the meaning of conversion and its application in daily life, and what is expected of a converted person. They will also learn that Christians face struggles, trials, and temptations every day, but these are part of the growth process. Furthermore, the reader will learn about the spiritual disciplines of the believer and how they can influence not only behavior but also personal development. This book teaches about worship, prayer, fasting, Bible study, and the importance of gathering together to worship God. Along these lines, the student will explore ways to implement these practices in daily life. Finally, this book teaches about the importance of getting along with others, personal relationships, and how to serve God in this new life.
