Most human beings are sinners, but the beasts are innocent. Surely those without sin should receive the most kindness and love -- all except animals which are harmful... But to blessed animals the utmost kindness must be shown, the more the better. Tenderness and loving-kindness are basic principles of God's heavenly Kingdom. Ye should most carefully bear this matter in mind.
