Why must our wants be under control?

Genesis 3:1-7The serpent was the shrewdest of all the wild animals the Lord God had made. One day he asked the woman, “Did God really say you must not eat the fruit from any of the trees in the garden?” “Of course we may eat fruit from the trees in the garden,” the woman replied. “It’s only the fruit from the tree in the middle of the garden that we are not allowed to eat. God said, ‘You must not eat it or even touch it; if you do, you will die.’” “You won’t die!” the serpent replied to the woman. “God knows that your eyes will be opened as soon as you eat it, and you will be like God, knowing both good and evil.” The woman was convinced. She saw that the tree was beautiful and its fruit looked delicious, and she wanted the wisdom it would give her. So she took some of the fruit and ate it. Then she gave some to her husband, who was with her, and he ate it, too. At that moment their eyes were opened, and they suddenly felt shame at their nakedness. So they sewed fig leaves together to cover themselves.

In order to damage the relationship between God and humans, Satan enticed them to want something they were told they could not have. That want was provoked by causing Eve to distrust her Creator and conclude God was unfairly withholding something desirable. Our wants have continued to be a universal point of vulnerability to sin for humans. The capacity to desire in itself is not evil, but our condition as sinners makes many of our wants selfish or unwise.

Romans 7:14-25So the trouble is not with the law, for it is spiritual and good. The trouble is with me, for I am all too human, a slave to sin. I don’t really understand myself, for I want to do what is right, but I don’t do it. Instead, I do what I hate. But if I know that what I am doing is wrong, this shows that I agree that the law is good. So I am not the one doing wrong; it is sin living in me that does it. And I know that nothing good lives in me, that is, in my sinful nature. I want to do what is right, but I can’t. I want to do what is good, but I don’t. I don’t want to do what is wrong, but I do it anyway. But if I do what I don’t want to do, I am not really the one doing wrong; it is sin living in me that does it. I have discovered this principle of life—that when I want to do what is right, I inevitably do what is wrong. I love God’s law with all my heart. But there is another power within me that is at war with my mind. This power makes me a slave to the sin that is still within me. Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death? Thank God! The answer is in Jesus Christ our Lord. So you see how it is: In my mind I really want to obey God’s law, but because of my sinful nature I am a slave to sin.

Our wants may be good or bad, but we often find ourselves unable to get what we want and be what we want to be, even when those objectives are good. Our frustration over wants remind us not only that we live in a fallen world, but that God has promised to provide us help in reaching what we want that is good for us.
