Christ fulfilled the law perfectly for us ... something we can never DO...
When ever we hear we are to DO something it is the LAW ...the LAW is DO ...GRACE is DONE
What the unsaved do not know, because they have not experienced it, is the heart change God does in His kids.. no longer driven by being slaves to sin, we are slaves to Christ and His righteousness. .no longer righteousness by works of the flesh ...but by the spirit of God
The next time someone questions me on this, I will have an answer :) (as all of us are supposed to have!)
thank you.
