Two things always go together in the experience of a genuine believer

(Arthur Pink, "The Doctrine of Sanctification" 1937)

Two things always go together in the experience of a genuine believer:
  a growing discovery of the vileness of self, and
  a deepening appreciation of the preciousness of Christ.

"Behold, I am vile!" Job 40:4
"O wretched man that I am!" Romans 7:24

"Yes, He is altogether lovely!" Song of Songs 5:16
"To you who believe, He is precious!" 1 Peter 2:7
