181:2.4
“Once we called you and your brother sons of thunder. You started out with us strong-minded and intolerant, but you have changed much since you wanted me to call fire down upon the heads of ignorant and thoughtless unbelievers. And you must change yet more. You should become the apostle of the new commandment which I have this night given you. Dedicate your life to teaching your brethren how to love one another, even as I have loved you.”
