"There is not a righteous man on earth who does what is right and never sins." Ecclesiastes 7:20
It's only natural that we take our eyes off the invisible God and put them on something or someone visible here on earth. Remember that every human being has the pontential, and the probability, of letting us down. No human being can live up to our expectations, no one is righteous enough. The only exception is the Savior sent by God. He is the one we need to turn our eyes to because He will never disappoint us.
