I enjoy interacting with other Christians on biblical topics and to encourage others. Maybe I can encourage someone what I've been through myself on my way back to Jesus.
The point I am making is this: saved or not-the 'law' is still valid for teaching and following Christ moving towards the goal of righteousness. You cannot know the path to righteousness that leads to Christ without the law.
You can however accept salvation without knowing the law-BUT; then you are obligated to further your education in pursuit of a relationship with Jesus Christ when you accept His gift.
We are not at free will if we are in obedience and subjection to Christ-we are called to obey. Well what do you obey if you know not the law? Yourself?
As Christians we are called to rebuke and teach the next generation to put them on the path to righteousness. This is done using the 'law'.
When we truly walk in the Spirit-there is no law against it; for we are walking with Christ directly and the chains of the world fall off.
I wasn't trying to argue-did you read the scripture I posted above? Just trying to show you what the scripture says-from Paul's own hand.
