The Ten Commandments were never meant as a means of obtaining perfection. Instead, they, as well as the other 603 commandments of what we call the Old Testament, were the means of attaining a cohesive, strong society. But there it ended. The promise which God made to the Hebrews as a reward for their keeping his laws and commandments, including The Ten Commandments, shows that there was to be no thought of using those laws in order to become perfect. Here is that promise:
If you pay attention to these laws and are careful to follow them, then the Lord your God will keep his covenant of love with you, as he swore to your forefathers. He will love you and bless you and increase your numbers. He will bless the fruit of your womb, the crops of your land - your grain, new wine and oil - the calves of your herds and the lambs of your flocks in the land that he swore to your forefathers to give you. You will be blessed more than any other people; none of your men or women will be childless, nor any of your livestock without young. The Lord will keep you free from every disease. He will not inflict on you the horrible diseases you knew in Egypt, but he will inflict them on all who hate you. (Deuteronomy 7:12-15,NIV)
There's the agreement. The Hebrews kept God's laws and commandments in this life; the Hebrews were rewarded in this life. It was a pragmatic, here-and-now contract that had nothing whatsoever to do with there even being an afterlife, much less their being able to obtain it. To them death was a wall, not a door. You lived, you died, the end.
In order to see what our attitudes and actions are to be as Christians, we must look to the New Testament for the answer. And that answer is a code of conduct that quite literally requires the direct intervention of the Holy Spirit himself for us to successfully follow:
So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want. But if you are led by the Spirit, you are not under law.
The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Let us not become conceited, provoking and envying each other. (Galatians 5:16-26,NIV)
Take a good look at 'the acts of the sinful nature' and 'the fruit of the Spirit'. Do you notice that in both cases you're seeing a list that is primarily made up of emotions rather than actual actions? We are told that we are not to have the feelings that lead us to perform evil acts (acts of the sinful nature), but we are to have the feelings that serve as the impetus for performing acts that are truly righteous (the fruit of the Spirit). So how do we program our feelings so as to rid ourselves of those that lead to acts that are evil, while nurturing those that lead to acts which are righteous?
We don't; God does.
We can no more change our feelings than a leopard can change his spots into stripes. That's why we need the Holy Spirit himself. He fights aginst our sinful nature in paragraph #1 of this passage. He brings the fruit with him and implants that fruit in us in paragraph #3. We also are told to 'keep in step' with him, which implies that he is ahead of us, not behind us. We follow his lead, letting him 'clear the way' for us as we proceed through life. As with our salvation, so with our conduct as Christians we depend entirely on God's actions rather than our own in order to succeed.
God bless-
