Be in perfect unity. Never become angry with one another….Love the creatures for the sake of God and not for themselves. You will never become angry or impatient if you love them for the sake of God. Humanity is not perfect. There are imperfections in every human being, and you will always become unhappy if you look toward the people themselves. But if you look toward God, you will love them and be kind to them, for the world of God is the world of perfection and complete mercy.
