Biblical knowledge
"Reader, remember this: if your biblical knowledge
does not now affect your heart, it will at last, with
a witness, afflict your heart.
If it does not now endear Christ to you, it will at
last provoke Christ the more against you.
If it does not make all the things of Christ to be
very precious in your eyes, it will at last make
you the more vile in Christ's eyes."
-Thomas Brooks
