I don't think those that are in Christ think they are free to sin yet they still understand that the righteousness from God through Christ Jesus was/is credited to us by grace and not by works of the law. The importance is found in faith expressing itself through love.one thing many people don't realize is that keeping God's 10 commandments or His 613 laws was NEVER God's method to be saved - even in the 1st 5 books of the Bible -
iow jews never kept God's commands to be saved and still don't keep God's laws to be saved - anyone keeping God's laws to be saved is misunderstanding the purpose God gave us His holy laws
they are God's wisdom for a good lifestyle
if we who are BA decide that we can now kill/lie/steal/etc we are greatly deceiving ourselves and misunderstanding God's grace in it's fullness - God's grace is ALSO God's ability working in us helping us to stop sinning and live a good lifestyle
a good lifestyle blesses everyone - a sinful lifestyle hurts everyone - salvation is a separate issue - even the OT says God ALONE saves - Psalms 62:5-7
And the Spirit in us does help us in our weaknesses.
We believe in a resurrection of the righteous and the unrighteous. So we keep a clear conscience before God.
