Our brain is the most complex organ we have. It has 100 billion nerves with trillions of connections. It receives input from our eyes, ears, nose, taste buds, and touch. It processes the data, and then sends out messages all over the body telling it how to act. The brain keeps a record of every experience we ever had, even those we may think are forgotten. Perhaps one reason God created us with brains is so we can retain memories of what God has done for us. Our minds enable us to recall the past, to function in the present, and to anticipate the future. By recalling God’s past blessings, we respond with thanksgiving and gratitude. This, in turn, should lead us to worship and obey God who did it all. It is why God told ancient Israel to celebrate what God had done for them. We read in Numbers chapter 9 where God said to Moses, “Tell the Israelites to celebrate the Passover at the prescribed time … Be sure to follow all my decrees and regulations concerning this celebration.” By recalling their deliverance at God’s hands, they reaffirm their dependence upon Him. This in turn, should lead them to worship and obey God. Today, unless we regularly recall and reaffirm our dependence on God, we will slide away from His sufficiency into the abyss of a worthless life.
