Maybe Calvin became a Calvin over time
maybe he just came to understand that though we are called into HIS WORK, HE alone is the ONE who opens the eyes and the ears of the heart so that a man can both see and hear THE GOSPEL, so that THE GOSPEL will be received as it should be received (from GOD and not from men)
i believe that Christians might misjudge Calvin and those who hold to his understanding, thinking that, just as the poster mentioned, "chillax"...like the lazy servant who knows HIS MASTER's WORK and instead of casting the seeds, he hoards the seeds and does not go out
i don't believe that this is what Calvin was saying when he spoke of election. I don't think it stopped him from preaching the GOSPEL. At least, it shouldn't have
