Mark 4:21-23

And He said unto them, Is a candle brought to be put under a bushel, or under a bed? And not be set on a candlestick.  For there is nothing hid, which shall not be manifested; neither was anything kept secret, but that it should come abroad. If any man has ears to hear, let him hear. 

Our thoughts and our lives are not a secret to God.  Whether we like it or not, what happens in our private life always bubbles over into our public life.  We may not share our problems, but our actions and reactions will tell the story. If we focus on God and the word of God firmly in our lives, that is what everyone will see.  Be of good courage and keep the faith, and the light will shine.
