I think what His least, Roger, and I are getting at is if you still sin (just as we all do), what practical application does what you say have? If you have entered into His rest and ceased from labors and are in a place where sin touches you not, why is it you still sin? I guess we are missing the connection between "a place where sin touches you not" and "I still sin." How does sin not touch you yet you still sin like the rest of us? Please tell me you see a disconnect there.
On a side note, if you plan on teaching, you need to figure out a way to break things down to the lowest common denominator so that even a child can understand it without "Christianese", Theology Speak, or vague analogies. Say what you mean in plain simple terms that have a practical application. It is one of the hardest (but most helpful) things I ever learned as a pastor.
This is obviously from a different context, but it really drives the point home...
So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air.
For what mortal has ever heard the voice of the living God speaking out of fire, as we have, and survived? ~ Deuteronomy 5:26
If you're not prepared to risk your very life for your "enemy" you have no right to speak to him of love. ~ Daughter
Many say they are called... but I am pretty convinced that with many of them it was the wrong number. ~ Project Peter
