There are all kinds of books like this on the market. I usually get nervous when they talk about “power”. There is a tendency among us to do one of two equally damaging things – expect perfection or condone sin. We can’t accept and be patient with the weaknesses among us. Good thing Christ can and does. This is Luther on 1 Corinthians 5:6-8 that talks about “leaven”.
This is Christ’s thought when he says to his disciples (Jn 15, 3), “Already ye are clean because of the word which I have spoken unto you,” and in the same connection he declares that the branches in him must be purged that they may bring forth more fruit. And to Peter– and to others he says (Jn 13, 10), “He that is bathed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.” These passages, as is also stated elsewhere, teach that a Christian by faith lays hold upon the purity of Christ, for which reason he is also regarded pure and begins to make progress in purity; for faith brings the Holy Spirit, who works in man, enabling him to withstand and to subdue sin.
16. They are to be censured according to whose representations and views a Christian Church is to be advocated which should be in all respects without infirmity and defect, and who teach that, when perfection is not in evidence, there is no such thing as the Church of Christ nor as true Christians. Many erring spirits, especially strong pretenders to wisdom, and precocious, self-made saints, immediately become impatient at sight of any weakness in Christians who profess the Gospel faith; for their own dreams are of a Church without any imperfections, a thing impossible in this earthly life, even they themselves not being perfect.
17. Such, we must know, is the nature of Christ’s office and dominion in his Church that though he really does instantaneously, through faith, confer upon us his purity, and by the Spirit transforms our hearts, yet the work of transformation and purification is not at once completed. Daily Christ works in us and purges us, to the end that we grow in purity daily. This work he carries on in us through the agency of the Word, admonishing, reproving, correcting and strengthening; as in the case of the Corinthians through the instrumentality of Paul. Christ also uses crosses and afflictions in effecting this end.
He did not come to toil, to suffer and to die because he expected to find pure and holy people. Purity and holiness for us he has acquired in his own person to perfection, inasmuch as he was without sin and perfectly pure from the moment he became man, and this purity and holiness he communicates to us in their flawless perfection in so far our faith clings to him. But to attain personal purity of such perfection requires a daily effort on the part of Christ, until the time shall have come that he has wrought in us a flawless perfection like his own.
