Ever wonder why some "Christians" seem no different than anyone else?
dubya for instance?
Acts 26:20 "...but [I] kept declaring both to those of Damascus first, and also at Jerusalem
and then throughout all the region of Judea,
and even to the Gentiles,
that they should repent and turn to God,
performing deeds appropriate to repentance.
Do Christians still sin? Sure we do, but when we sin it really bugs us. It hurts us because we've failed God again. We can't sin habitually simply because it hurts too much. God won't let us get away with it without causing us enough pain to motivate us to stop.
