Description: Personalized sex education tailored to age and gender! Help instill biblically grounded values about sex in your precious children! As various sex crimes have become a growing social issue, the need for sex education has become more urgent than ever. In particular, in today's social and cultural climate where even sexual identity is being called into question, biblical sex education has become more important than ever. Yet many parents and teachers still feel uncomfortable and embarrassed, unsure of where or how to begin teaching this topic. While adults hesitate, there is real concern that children may pick up incorrect information about sex through social media or friends. The 'Biblical Sex Education Series for Our Children' was created out of this very concern. A key feature of this book is that it is divided into four stages by age and organized by gender, allowing for tailored sex education. Through this series, children can receive age- and gender-appropriate sex education grounded in biblical values — from early childhood, when children first begin noticing the differences between boys and girls, all the way through adolescence, when accurate and detailed knowledge about sex becomes essential. While this series cannot provide every piece of knowledge about sex, it offers a clear and reliable guide to biblical sex education. We hope that parents and teachers will use this book as an opportunity to have honest, natural conversations about sex together with their children. [Series Introduction] Biblical Sex Education Series for Our Children (Revised Edition) The Next Generation Research Institute, established with the support of Bundang Woori Church (Senior Pastor Lee Chan-soo), was founded to help build up families, churches, the next generation, their parents, and next-generation ministry workers based on biblical values. As part of its ministry to support families, the institute discovered and supervised the 'Learning about Sex Series' from Concordia Publishing House, a Christian publisher in the United States, and introduced it in Korea under the title 'Biblical Sex Education Series for Our Children,' so that our children could receive sound, biblical sex education. As children today grow up much faster than parents expect, many Christian parents and teachers deeply struggle with the question of 'when and how' to provide sex education. The 'Biblical Sex Education Series for Our Children' was created to address exactly this concern. Divided into four stages from early childhood through adolescence, the series conveys what children at each age level need to know, grounded in the truth of God's created order. Another defining feature of this series is that it is separated into books for boys and girls, allowing for sex education tailored to both age and gender. In particular, this newly revised edition preserves the biblical values found in the original English text while adapting the language and stages to better fit Korean sensibilities. It also includes guide videos explaining 'why biblical sex education matters' and 'key points for each stage,' helping readers make the most of the series. In addition, a companion workbook (sold separately) has been published to help families and churches carry out biblical sex education more effectively. We hope this series will have a positive impact on building a healthy culture around sex within the Korean church.
