I was in that kind of teaching for a while. It tends to have people looking to themselves and trusting in their works, when they should be looking to Jesus and trusting in His promises. Jesus is the One who sanctifies. We do not sanctify ourselves. Hebrews 2:11 .
An Exposition Of Hebrews by Arthur Pinks comments on Hebrews 2:11
But what is meant by "He that sanctifieth and they who are sanctified"? The Sanctifier is Christ Himself, the sanctified are the many sons who are being brought to glory. "The source and power of sanctification are in the Son of God our Savior. We who were to be brought unto glory were far off from God, in a state of condemnation and death. What could be more different than our natural condition and the glory of God which we are awaiting?
Condemned on account of our transgressions of the law, we lived in sin, alienated from God, and without His presence of light and love. We were dead; and by ‘dead’ I do not mean that modern fancy which explains death to mean cessation of existence, but that continuous, active, self-developing state of misery and corruption into which the sinner has fallen by his disobedience. Dead in trespasses and sins, wherein we walked; dead while living in pleasing self (Eph. 2:1, 2, 1 Timothy 5:6).
What can be more opposed to glory than the state in which we are by nature? and if we are to be brought into glory, it is evident we must be brought into holiness; we must be delivered and separated from guilt, pollution, and death, and brought into the presence of God, in which is favor, light, and life—that His life may descend into our souls, and that we may become partakers of the Divine nature. "Christ is our sanctification. ‘By one offering He hath perfected forever them that are sanctified’ (Heb. 10:14).
By the offering of His body as the sacrifice for sin, He has sanctified all that put their trust in Him. To sanctify is to separate unto God; to separate for a holy use. We who were far off are brought nigh by the blood of Christ. And although our election is of God the Father (who is thus the Author of our sanctification, Jude 4), and the cleansing and purification of the heart is generally attributed to the Holy Spirit (Titus 3:4,5), yet is it in Christ that we were chosen, and from Christ that we receive the Spirit, and as it is by the constant application of Christ’s work and the constant communication of His life that we live and grow.
Christ is our sanctification. "We are sanctified through faith that is in Him (Acts 26:18). By His offering of Himself He has brought us into the presence of God. By the Word, by God’s truth, by the indwelling Spirit, He continually sanctifies His believers. He gave Himself for the church, ‘that He might sanctify and cleanse it by the washing of water by the Word’ (Eph. 5:26). ‘Sanctify them through Thy truth’ (John 17:17; 15:3). "Christ Himself is the foundation, source, method, and channel of our sanctification.
