Well known Calvinist author R.C. Sproul says the following:
"When the term 'monergism' is linked with the word 'regeneration' the phrase describes an action by which God the Holy Spirit works on a human being without that person's assistance or cooperation".
According to the Calvinists being made alive spiritually or being regenerated happens prior to one believing. Here is how Sproul explains that:
"When speaking of the order of salvation (ordo salutis), Reformed theology always and everywhere insists that regeneration precedes faith. Regeneration precedes faith because it is a necessary condition for faith...when Reformed theology says regeneration precedes faith, it is speaking in terms of logical priority, not temporal priority. We cannot exercise saving faith until we have been regenerated, so we say that faith is dependent on regeneration, not regeneration on faith."
According to Sproul one must be regenerated or be made spiritually alive before he can believe the gospel. However, the following words of the Apostle John demonstrates that spiritual life comes as a result of believing:
"Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name" (Jn.20:30-31).
This in itself thoroughly destroys the idea that one is made alive spiritually or regenerated before coming to faith.
