I think so, because it's Jesus righteousness that makes alive, apart from that we are completely a corpse......

since our hope lies in Jesus and we have been saved, are saved will be saved

and sin will continue to be a burden although we become further exercised in faith as we grow in grace, I think it's proper to preceive myself as totally depraved, at least in my old flesh/sinful nature....

I probably would not call other regenerate totally depraved but when speaking of mankind in general and the external church I would use that term....

maybe I'm kind of changing my answer midway thru, for myself yes...for others who are regenerate, I would not label them as such......

The mercy of God is necessary not only when a person repents, but even to lead him to repent, Augustine
