Does a soul have age?

The actual soul does not age permanently though it carries the impress of the body when it first comes over. 

By degrees, freed from material cares, the signs of age disappear and the spirit body looks like that of an adult in the prime of life and in perfect health. When you leave the earth life, you appear for a short time much as you did when you left it, but the moment you commence to learn heavenly wisdom, that moment you commence to grow young and beautiful―you do not go back to childhood in your appearance, neither do you ever again have the same appearance that you had in the earth life, but as you throw off error after error, and take on wisdom, love and truth, you become perfect and beautiful in your outward appearance and every mark that time has left upon you is one of perfection and beauty. 

Some of the angels here are so bright and glorious that even we, that have been here many years, cannot behold them, and those that come here as children grow in love and wisdom until they appear as full grown men and women, and then they go on like the rest.
