This is what I have been calling "the walk"

And I have been calling that very thing "work", and so does St. Paul who wrote the passage.

I probably call sanctification a "walk" because I am drawn to the Apostle John, and he uses that term (emphasis mine):

This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us. - I John 1:5-10
