In the book of Luke Chapter 6 Verses 45-47

 45)   “A good man produces goodness from the good in his heart; and evil man produces evil out of his store of evil.   Each man speaks from his heart’s abundance.   46) Why do you call me ‘Lord, Lord,’ and not put into practice what I teach you? 47)   Any man who desires  to come to me will hear my words and put them into practice.   I will show you with whom he is to be compared.”
