“Justification is the means whereby we appropriate the saving act of God in the past, and sanctification the promise of God's activity in the present and future...Justification is primarily concerned with the relation between man and the law of God, sanctification with the Christian's separation from the world until the second coming of Christ...Justification is the new creation of the new man, and sanctification is his preservation until the day of Jesus Christ.”

“Sanctification means that the Christians have been judged already, and that they are being preserved until the coming of Christ and are ever advancing towards it.”

“Christian community is like the Christian's sanctification. It is a gift of God which we cannot claim. Only God knows the real state of our fellowship, of our sanctification. What may appear weak and trifling to us may be great and glorious to God. Just as the Christian should not be constantly feeling his spiritual pulse, so, too, the Christian community has not been given to us by God for us to be constantly taking its temperature. The more thankfully we daily receive what is given to us, the more surely and steadily will fellowship increase and grow from day to day as God pleases.”

“Nothing can be known either of God or man until God has become man in Jesus Christ.”

“Just as the separation of Church and world became visible only in their continuous conflict, so also does personal sanctification consist in the conflict of the Spirit against the flesh. The saints are only conscious of the strife and distress, the weakness and sin in their lives; and the further they advance in holiness, the more they feel they are fighting a losing battle and dying in the flesh. "They that are of Christ Jesus have crucified the flesh with the passions and lusts thereof" (Gal. 5.24). They still live in the flesh, but for that very reason their whole life must be an act of faith in the Son of God, who has begun his life in them (Gal. 2.20). The Christian dies daily (I Cor. 15.31), but although this may mean suffering and decay in the flesh, the inward man is renewed day by day (II Cor. 4.16). The only reason why the saints have to die in the flesh is that Christ through the Holy Spirit has begun to live his life in them. The effect of Christ and his life on the saints is that they die after the flesh. There is no need for them to go out of their way to look for suffering: indeed that would only mean a return to the self-assertion of the flesh. Every day Christ is their death and Christ is their life.”

“The community of the saints is not an "ideal" community consisting of perfect and sinless men and women, where there is no need of further repentance. No, it is a community which proves that it is worthy of the gospel of forgiveness by constantly and sincerely proclaiming God's forgiveness...Sanctification means driving out the world from the Church as well as separating the Church from the world. But the purpose of such discipline is not to establish a community of the perfect, but a community consisting of men who really live under the forgiving mercy of God.”

“He stands between us and God, and for that very reason he stands between us and all other men and things. He is the Mediator, not only between God and man, but between man and man, between man and reality. Since the whole world was created through him and unto him (John 1.3; I Cor. 8.6; Heb. 1.2), he is the sole Mediator in the world. Since his coming man has no immediate relationship of his own any more to anything, neither to God nor to the world; Christ wants to be the mediator. Of course, there are plenty of gods who offer men direct access, and the world naturally uses every means in its power to retain its direct hold on men, but that is the very reason why it is so bitterly opposed to Christ, the Mediator.”
