This is not the behaviour of a repentant individual even though, unfortunately, it is often the mark of a modern Christian. Many Christians cry out to Jesus to give them the strength to resist the temptation to sin. Then, when they succumb to temptation again, it seems to them that Jesus has let them down, that he's to blame.
This behavior does not match that of a genuinely remorseful person, yet it is often seen among modern Christians. Many Christians appeal to Jesus for the resolve to resist sin, but when they fail, they attribute their downfall to Jesus' failure.
