The 10 commandments are not just for kids. Every adult should memorize them and abide by them. Imagine what would happen to our world if people actually followed the ten commandments that were given to Moses by God. They are laid out in detail in Exodus 20 in the Bible. It is part of the Law given to the 12 tribes of Israel which they were unable to keep. They are not the only ones, however. Have you been able to keep all ten all of your life? If you have broken just one of them just once, then that means that you will need to spend eternity separated from God in a burning lake of fire. Not a pleasant thought. But you should think about it seriously because your eternal destination depends on it. Knowing that man could not keep God's holy law, God made a plan of salvation in order to save mankind from spending eternity in hell. His plan is known as the "new promise" and outlined in the New Testament. The plan was for God himself to come to earth in the form of a man Jesus and suffer and die for your sins. Now how amazing is that? Is there anyone else who can die for your sins so that they will be totally removed so that you can enter into God's presence?
