Atonement & Law : Inverse Relationship

"Take away the law, and there is no longer any need of atonement. Contrawise: if there is still atonement, there is still law."
The Sanctuary Service p.281 M.L.Andreasen

What shall we say then?

Is the law sin?

God forbid.

Nay, I had not known sin, but by the law:

for I had not known lust,

except the law had said,

Thou shalt not covet.

Romans 7:7
