In Matt. 15:13 we have this same doctrine of cleansing expressed in the words of Jesus: "Every plant, which my heavenly Father hath not planted, shall be rooted up." While it is true that Jesus was speaking of the doctrines of the Pharisees in this instance, we can see beyond the simple doctrines and traditions of men, which are but the outgrowth of this root of depravity which our heavenly Father never planted in the nature of man. The depraved heart is the fertile soil which spontaneously grows all these evil things which Jesus mentions in this parable. The root is there, and so long as it remains, there cannot be a satisfactory Christian life. But the heavenly decree has been uttered by the Redeemer himself, that this plant shall be rooted up, which rooting up can be testified to by thousands of blood-washed saints today. Many plain scriptures teach us that this experience of heart purity was a recognized fact in the apostolic days. Jesus taught that it was attainable and told of its blessings when in Matt. 5:8 he speaks of the pure in heart. John writes: "And every man that hath this hope in him purifieth himself, even as he is pure." Paul says that "the end of the commandment is charity out of a pure heart" (1 Tim. 1:5), and in the same letter he writes: "Holding the mystery of the faith in a pure conscience."--Chap. 3:9. Also in Chap. 4:12, he writes: "Let no man despise thy youth: but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity." In Chap. 5:22, he says, "Keep thyself pure." In 2 Tim. 2:22 we are taught that many of the saints had this experience of cleansing: "Flee also youthful lusts; but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart." The prophet Malachi saw the glorious fullness of this gospel salvation as he beheld and spake by the Spirit: "And he shall sit as a refiner and purifier of silver and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the Lord an offering in righteousness."--Mal. 3:3.
