Again, Jesus gave us the sacrament of confession because he understood our sinful nature, but you have to go and sin no more, and keep on trying no matter how many times you fail.  Jesus gave us the Eucharist so we can grow in strength with him, but you have to be in a state of grace to receive him.  What is the point of receiving the Eucharist, the real presence of Jesus Christ, if you can't even be bothered to change your sinful ways?  St. Paul even said that this puts your soul in real jeopardy because only God knows the time and the place you leave this earth.
