It's not a choice to live a sinful life. What I'm saying is that we will anyway. Those who convince themselves they are good enough to be sinless are the liars. I don't think Jesus started this honest covenant of faith for peace with God meant for us to walk around sounding like Pharisees . . . and a LOT of us do that. Jesus didn't get along with the Pharisees, it's in the Bible . . . Christians.
If the Law of Moses was the established set of rules to discover what sin is, then that is the standard by which I can say, "We all are living in sin, whether sin is a choice or not." The really dangerous thing, spiritually speaking, is to think that you accomplished living without sin. That is a great step toward spiritual pride, and it is a lie.
Romans 3
19 Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. 20 Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin.
edit: See what gw said?
That is what a legalist looks like. A nice one though. I've seen some who are totally invested in their own corruption of the Laws of Moses and are mean about it. gw is being nice. But the same thing shows up; an expectation that there is NOTHING wrong with gw's behavior, even when no none is looking. We can see gw as a better behaved individual that God sees as morally superior, and gw might be morally superior to me, but neither he nor I am the standard for sin. The standard of sin is 613 laws that even gw doesn't do . . . or perhaps doesn't even know about.
