When is our willpower a weakness?

Romans 6:19-23Because of the weakness of your human nature, I am using the illustration of slavery to help you understand all this. Previously, you let yourselves be slaves to impurity and lawlessness, which led ever deeper into sin. Now you must give yourselves to be slaves to righteous living so that you will become holy. When you were slaves to sin, you were free from the obligation to do right. And what was the result? You are now ashamed of the things you used to do, things that end in eternal doom. But now you are free from the power of sin and have become slaves of God. Now you do those things that lead to holiness and result in eternal life. For the wages of sin is death, but the free gift of God is eternal life through Christ Jesus our Lord.

Romans 7:5-6When we were controlled by our old nature, sinful desires were at work within us, and the law aroused these evil desires that produced a harvest of sinful deeds, resulting in death. But now we have been released from the law, for we died to it and are no longer captive to its power. Now we can serve God, not in the old way of obeying the letter of the law, but in the new way of living in the Spirit.

Human willpower apart from God’s supporting presence is under the direction of our fallen nature. We naturally lean toward disobedience. We cannot escape sin by sheer willpower. We have to be set free from that captivity by God, who made that escape possible through what Jesus accomplished on the cross by breaking the power of sin and death. We are now free to exercise our willpower in the service of God’s Spirit.

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.

As long as we live this side of eternity we will deal with our tendency to fall short in our actions for God even when we know what we should be doing. The weakness of our willpower makes it crucial that we live humbly and in repentance before God to experience his freeing forgiveness in Christ each day.
