The devil and temptations also do give occasion unto us somewhat to learn and understand the Scriptures, by experience and practice. Without trials and temptations we should never understand anything thereof; no, not although we diligently read and heard the same.
- Martin Luther
You have ordained Your precepts, that we should keep them diligently.
- Psalm 119:4
The Bible is the textbook, and it is to be searched diligently—not as we would read a book among many books. It must be to us the book that meets the wants of the soul.
- Ellen White
Thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.And these words, which I command thee this day, shall be in thine heart:And thou shalt teach them diligently unto thy children.
