Months had gone by. The time and energy I had spent teaching the Pentateuch to my son was well worth it. We had finally finished the first five books of the Bible. My son was receiving a first rate Bible study. Or so I thought. Much to my disappointment, a brief question and answer session revealed that my boy couldn't remember the events of Abraham's life. What happened? We read a chapter of the Bible each day, beginning with Genesis all the way to Deuteronomy. We reviewed the major biblical events at the start of each day. What did I do wrong? He could answer the questions to the Westminster Shorter Catechism without any problem. Why couldn't he remember the Bible? Then it struck me. He needed a catechism of the Bible. And so did I. How many times have I found myself trying to recall the specific events of a biblical event, only having to reread the story. Many people are this way. We easily forget information if we are not vigilant in reviewing it. This catechism of the historical books of the Old Testament is the result of months of plodding study. Each day I read one chapter of the Bible to my two oldest children, and they memorized the answers to several questions. By the time we had finished the book of Joshua, my children knew the book as well as the kids who were raised in the Puritan era. We went on to the book of Judges. Once a week we returned to the book of Joshua to review the questions. When we arrived at the end of Judges we continued on to Ruth. Judges was added to our list of books to review weekly. The problem was solved. We will need to return to the book of the Law eventually. But for now we have proceeded to the New Testament. Lord willing, in a few months, a catechism of the Gospels and Acts will be completed and available for purchase. Catechisms have been used throughout the history of the church to communicate God's truth. The human mind is too often like a leaky bucket of water. Information we once had stored has disappeared over the course of time. As a weightlifter must train consistently to keep the gains he has made, so it is with the spiritual athlete. God has given us many tools to grow our spiritual life. Bible reading and prayer are two essential duties of every Christian. There are helps that we have relating to both that many before us did not have. This catechism is just that: a tool, a help. It is written so that children as young as five are able to easily memorize the answers. It is also a great way for adolescents to learn the Bible. And if you are like me, an adult with children or grandchildren who finds it more difficult to remember things than it used to be, this short book will be a benefit. So it is for everyone, the young and the old. It is for Sunday School teachers studying an historical book of the Bible with their class. It is for homeschool parents who desire a solid, biblical education for their children. It is for the head of the family for use at the family altar. And it is for God's child who desires to have a stronger relationship with Him through the knowledge of His Word. Stephen Wuori is from Massachusetts.
