“The church is not a theological classroom. It is a conversion, confession, repentance, reconciliation, forgiveness and sanctification center, where flawed people place their faith in Christ, gather to know and love him better, and learn to love others as he designed.”1 – Paul David Tripp
“While the agent of renovation is the Divine Spirit, and the condition of renovation is our cleaving to Christ, the medium of renovation and the weapon which the transforming grace employs is ‘the word of the truth of the gospel,’ whereby we are sanctified.” – Alexander MacLaren
“There are three things which the true Christian desires in respect to sin: Justification, that it may not condemn; sanctification, that it may not rein; and glorification, that it may not be.” – Richard Cecil
“Tell me not of your justification, unless you have also some marks of sanctification. Boast not of Christ’s work for you, unless you can show us the Spirit’s work in you.” – J. C. Ryle
“Any man that is saved and sanctified can feel the fire burning in his heart, when he calls on the name of Jesus.” – William J. Seymour
“The sanctified body is one whose hands are clean. The stain of dishonesty is not on them, the withering blight of ill-gotten gain has not blistered them, the mark of violence is not found upon them. They have been separated from every occupation that could displease God or injure a fellow-man.” – A. B. Simpson
“Justification is the new creation of the new man, and sanctification his preservation until the day of Jesus Christ.” – Dietrich Bonhoeffer
“God never grants justification without also giving sanctification at the same time … Sanctification in us begins as an instantaneous act of the Holy Spirit and is carried forward by His continued action in our lives.” – Jerry Bridges
“Associate with sanctified persons. They may by their counsel, prayers, and holy example, be a means to make you holy.” – Thomas Watson
“We believe, that the work of regeneration, conversion, sanctification and faith, is not an act of man’s free will and power, but of the mighty, efficacious and irresistible grace of God.” – Charles Spurgeon
“Earnest souls who are attempting sanctification by struggle, instead of sanctification by faith, might be spared much humiliation by learning the botany of the Sermon on the Mount.” – Henry Drummond
“The Christian life requires hard work. Our sanctification is a process wherein we are coworkers with God. We have the promise of God’s assistance in our labor, but His divine help does not annul our responsibility to work (Phil. 2:12-13).” – R. C. Sproul
“Where science speaks of improvement, Christianity speaks of renovation; where science speaks of development, Christianity speaks of sanctification; where science of progress, Christianity speaks of perfection.” – James H. Aughey
“Some Christians overlook the blessing of sanctification, and yet to a thoroughly renewed heart this is one of the sweetest gifts of the covenant. If we could be saved from wrath, and yet remain unregenerate, impenitent sinners, we should not be saved as we desire, for we mainly and chiefly pant to be saved from sin and led in the way of holiness.” – Charles Spurgeon
“No one enters into the experience of entire sanctification without going through a ‘white funeral’ – the burial of the old life.” – Charles Stanley
