A person who cares nothing for praise or blame knows great inward peace….Praise does not make you holier than you are, nor blame more wicked. You are exactly what you are, and cannot ever be any better or worse than that, in the eyes of God. Attend to what is really within you, then, and you will not care what others say of you. People look at externals, but God looks at the heart. They weigh actions; God knows your intent….To feel no need of human support and assurance is a mark of inward confidence – of those who truly walk with God in their hearts.
