Will the real Christians stand up?

Thanks for this, but does Jesus ever say this? Jesus established a new covenant as I'm sure you know.

Mark 7:20-23
20 And He said, "What comes out of a man, that defiles a man.
21 "For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
22 "thefts, covetousness, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness.
23 "All these evil things come from within and defile a man."
(NKJ)

I guess I see this as what can happen when man follows the self, but I it seems to fall short of saying that man is incapable of overcoming sin. However there a number of verses that seem to ask man to overcome sin nonetheless. Do you see this differently?
