We gain knowledge when we go to class.
We gain knowledge when we read books.
We have understanding if we learn from the instructor.
We have understanding if we learn from the author.
Wisdom is the gift of utilization.
Knowledge is information.
Understanding is comprehension.
Wisdom is knowing what to do with it.
For the Lord giveth wisdom: out of his mouth cometh knowledge and understanding.
Proverbs 2:6 KJV
