"Here is the essence of perfect sincerity in conduct- to care for nothing but God's judgement on our actions, not to vary our attitude to suit the compnay we are in, not to hold one opinion when alone and adopt another in conversatoin, but to speak and act as in the sight of God who can read our inmost thoughts. Sincerity means trying to make the outward man more and more like the inner man by simply being true to ourselves, so that no human respect can make us false."
