Even a person who is relatively more spiritual [than others]
becomes more spiritual person as much as their thoughts, soul and spirit grow.
Just as a child is weak no matter how capable they are in sports,
a spiritual child is weak even if they do spiritual work with zeal.
Their thoughts, soul, and spirit have to grow.
By continually listening to the Word, acting upon it, and praying,
you should make yourself grow and mature just as the body grows,
just as a sapling grows, and just as a young fruit tree grows.
