God's precious spiritual knowledge is revealed in the words of Holy Scripture. Remember that we are told to live by every word of God (Matthew 4:4). Recall also that it was King David who said, "Your law is truth" (Psalm 119:142) and "the law of the LORD is perfect, converting the soul" (Psalm 19:7).
In summary, the Bible is the foundation or basis of knowledge. It shows the root cause of every problem that has plagued the human family since creation. God's Word reveals the true values by which we must live if we are to solve our massive relationship problems and the other seemingly insoluble dilemmas that threaten to overwhelm us.
Lesson 3 will explore the fascinating topic of Why Man? What is man and how is he related to God? Why was he made in God's image? Do we have an immortal soul? Is there a spirit in man? Will men and women either go to heaven or burn in hell? What is the reward of the saved? All these questions and many more will be answered in the next lesson.
