Thomas a Kempis

In truth, sublime words make not a man holy and just;
but a virtuous life maketh him dear to God.
I had rather feel compunction than know its definition.
If thou didst know the whole Bible by heart and the sayings of all the philosophers,
what would it profit it thee without the love of God and His grace.

Thomas a Kempis
Of the Imitation of Christ Bk. 1 Ch. 1 v. 3
