You may be exhausted with work—you may even kill yourself—but unless your work is interwoven with love, it is useless.
Don’t give in to discouragement. No more must you do so when you try to settle a marriage crisis or convert a sinner and don’t succeed. If you are discouraged, it is a sign of pride because it shows you trust in your own powers. Never bother about people’s opinions. Be humble and you will never be disturbed. It is very difficult in practice because we all want to see the result of our work. Leave it to Jesus.
