True charity is the desire to be useful to others with no thought of recompense.
Perform at least one act of charity of helping someone in need, or of simple kindness in secret each day. Keep your identity just between you and God; the recipient will remain unaware of their Secret Servant. They'll just think it's God being there for them – and they're right.
Chapter 6 - Teaching About Almsgiving. “[But] take care not to perform righteous deeds in order that people may see them; otherwise, you will have no recompense from your heavenly Father.
