The Witness to Entire Sanctification

QUESTION: Is there a definite witness to this grace [of entire sanctification]?

ANSWER: Yes, in general terms, I Cor. 2:21, "that we might know the things that are freely given to us of God," There is no specific text. The Spirit shining in our hearts shines on his own work. The sun that prints the pictures reveals it to us.
