Monergistic regeneration has to do, not with the whole process of redemption, but strictly with the initial condition or first step of our coming to faith. To be sure, Lazarus acted. He responded. He came forth from the tomb. But the crucial point is that he did none of these things while he was still dead. He did not respond to the call of Christ until after he had been made alive. His resurrection preceded his coming forth from the tomb. His restoration to life preceded his response.
