In the Christian world... it is believed that angels were created at the beginning, and that heaven was formed of them; and that the Devil or Satan was an angel of light, who, becoming rebellions, was cast down with his crew, and that this was the origin of hell.
Emanuel SwedenborgOne can see how great the delight of heaven must be from the fact that it is the delight of everyone in heaven to share his delights and blessings with others; and as such is the character of all that are in the heavens it is clear how immeasurable is the delight of heaven.
