The question is often asked by children, "Why do I have to study this?" And the answer is of course, "Because it will do you good." This is especially so when we come to the subject of history. Few things are so calculated to "do us good" as studying those things God has done in times past. This is the reason why the Psalmist in Psalm 78 emphasizes the importance of knowing the mighty works of God, "We will not hide them from their children, telling to the generation to come the praises of the LORD, and His strength and His wonderful works that He has done. For He established a testimony in Jacob and appointed a law in Israel, which He commanded our fathers, that they should make them known to their children; that the generation to come might know them, the children who would be born, that they may arise and declare them to their children, that they may set their hope in God, and not forget the works of God but keep His commandments." (Psalm 78:4-7).
