I had this feeling that there was a point where one could repent over n over and all that stuff, and it come to living two lives it seemed....

1Shout with the voice of a trumpet blast. Tell my people Israel of their sins! 2Yet they act so pious! They come to the Temple every day and seem delighted to hear my laws. You would almost think this was a righteous nation that would never abandon its God. They love to make a show of coming to me and asking me to take action on their behalf. 3`We have fasted before you!' they say. `Why aren't you impressed? We have done much penance, and you don't even notice it!'

I will tell you why! It's because you are living for yourselves even while you are fasting. You keep right on oppressing your workers. 4What good is fasting when you keep on fighting and quarreling? This kind of fasting will never get you anywhere with me. 5You humble yourselves by going through the motions of penance, bowing your heads like a blade of grass in the wind. You dress in sackcloth and cover yourselves with ashes. Is this what you call fasting? Do you really think this will please the LORD? Isaiah 58:1-5 (NLT)

Even taking fasting for repentance or sinning....I feel the same can and does apply.
