St. Faustina
“I will hide from people’s eyes whatever good I am able to do so that God Himself may be my reward. I will be like a tiny violet hidden in the grass, which does not hurt the foot that treads on it, but diffuses its fragrance and, forgetting itself completely, tries to please the person who has crushed it underfoot. This is very difficult for human nature, but God’s grace comes to one’s aid.”
