So, as sin comes in from the outside, it is immediately cleansed out of the person's life.
Does this not indicate that, because the person is continually being cleansed from all sin, that sin does not have the opportunity to take permanent residence in the person's life?
For it is immediately cleansed out of the person's life the moment that it begins to come in.
This is the result of walking in the light as He is in the light.
The fact that the Blood must remain available for man should tell you something.
John 1:8
"If we say that we have no sin, we deceive ourselves, and the truth is not in us"
