No, I believe that we cannot keep God's laws. I believe we know right from wrong, despite the law. Was there sin before the Law? Yes, but it wasn't imputed as such. The law only revealed it.
The law exposes sin. It defines some items, but has only a short list of right and wrongs. Jesus gave us a better way... God's way.
Sin. What is it? It is defined as "missing the mark". You quote Romans 6:15, but fail to note the passages before and after. The very next one (v16, and the following ones) explains Paul's thoughts better.
16Don't you know that when you offer yourselves to someone to obey him as slaves, you are slaves to the one whom you obey—whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness? 17But thanks be to God that, though you used to be slaves to sin, you wholeheartedly obeyed the form of teaching to which you were entrusted. 18You have been set free from sin and have become slaves to righteousness.
19I put this in human terms because you are weak in your natural selves. Just as you used to offer the parts of your body in slavery to impurity and to ever-increasing wickedness, so now offer them in slavery to righteousness leading to holiness. 20When you were slaves to sin, you were free from the control of righteousness. 21What benefit did you reap at that time from the things you are now ashamed of? Those things result in death! 22But now that you have been set free from sin and have become slaves to God, the benefit you reap leads to holiness, and the result is eternal life. 23For the wages of sin is death, but the gift of God is eternal life in[b] Christ Jesus our Lord.
LOL. Well, I still don't know what we are debating.
On the surface we are in agreement, but I can't help but think we are teaching a different Gospel. How do you define grace? I get the impression that you think Grace is a condition of the individual.
If you don't mind me asking...what denomination are you?
I'm curious. I was raised Catholic, but I am now a Baptist.
