You're right, of course. Chemotherapy is intended to save the patient. The Reformation, by the time it had progressed past its infancy, was intended to kill the patient.
LOL. God saves whom He will.
"...the restoration of the church is the work of God, and no more depends on the hopes and opinions of men, than the resurrection of the dead, or any other miracle of that description. Here, therefore, we are not to wait for facility of action, either from the will of men, or the temper of the times, but must rush forward through the midst of despair. It is the will of our Master that his gospel be preached. Let us obey his command, and follow whithersoever he calls. What the success will be it is not ours to inquire. Our only duty is to wish for what is best, and beseech it of the Lord in prayer; to strive with all zeal, solicitude, and diligence, to bring about the desired result, and, at the same time, to submit with patience to whatever that result may be." -- John Calvin
One can not kill what is already dead
Eph 2:5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
Eph 2:1 And you [hath he quickened], who were dead in trespasses and sins;
Col 2:13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
What the Reformation did was point out the natural state of unsaved men, one that had been hidden under years of "tradition and works"
