If the law was not made for the righteous, but the lawless then why?

1 Timothy 1:9 says this, but why do so many of us strive to keep the law? Is it because we are not perfected in the love of God? If one is perfected in love of God, then would it be safe to say that we have the very nature of God in us since God is love? If we have the nature of God within us, then won't we do righteousness by nature and not by constraint? My point is if Jesus said all the law and prophets hang on loving God with all your being and loving your neighbor as yourself, then we will not commit sin. So then how does such a love get in there that compels us to live in such a way? I believe one place to look is Matthew 18 where Jesus tells the parable of the debtors. When they couldn't pay what they owed, they were both forgiven of those debts. Jesus said the one that owed the most loved the most. The emphasis of this parable is ones inability to pay back what they owed, therefore creating a need to be forgiven. This created an immense love for the one who forgave them. There is more to it than this, but I don't want to make you read a whole lot. What do you think?
