Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts. 

-Isaiah 6:5

The day we realise that we are filthy as a result of our sins, the sooner we can be cleansed and purified.

There can be no salvation without an acknowledgement of sin. Once we accept our frailties as fallen beings, we can offer God true repentance and accept His eternal forgiveness.
