The soul gets nourished. A friend of mine used to teach that when we taught, the first thing forgotten was the content. The second thing forgotten was the style, how you taught what you taught. And the thing remembered longest was the attitude with which we taught. Our attitude nourishes the soul.
We also can bless the spirit of those present. We can awaken a thirst. A parishioner sent me the following, borrowing from Max Lucado.
"Train up a child in the way he should go, and when he is old he will not depart from it" (Proverbs 22:6).
The phrase "train up" descends from a root word that means to develop a thirst. Hebrew midwives awakened the thirst of a newborn by dipping a finger in a bowl of crushed dates and placing it in the baby's mouth. To "train up," then, means to awaken thirst.
Parents and teachers can awaken thirst "in the way [the child] should go."
What an awesome gift it is! This is a work of the Spirit to the spirit.
