"If  you feel that you are sinful and weak, you have a special right to Jesus' arms because He is the Good Shepherd who looks for lost sheep, those who are weak and helpless and who cannot keep up with the
flock."
  
(The Gift  of Faith, Third Edition, pg.83)

"When you sin or you are saddened, you do not trust God and you are not grateful, you are making yourself similar to the lost sheep."  (In the Arms of Mary, pg. 83)
