R.C. Sproul, one of the leading Calvinists in the world today, defines the concept of "monergistic regeneration" in the following way: "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" [emphasis added](R.C. Sproul, What is Reformed Theology? [Grand Rapids: Baker Books], 184). Therefore, by this reasoning, since a person plays no part in his regeneration then "regeneration precedes faith." Sproul says that "regeneration" occurs when we were dead in trepasses and are made alive together with Christ: "The key phrase in Paul's Letter to the Ephesians is this: '...even when we were dead in trespasses, made us alive together with Christ (by grace have you been saved)' (Eph. 2:5). Here Paul locates the time when regeneration occurs. It takes place 'when we were dead.' " (Sproul, Regeneration Precedes Faith). Let us look at a verse that speaks of the same thing so therefore we can understand that the following words are about "regeneration": "When you were dead in your transgressions and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our transgressions" (Col.2:12-13). We can also see that this regeneration does not happen until a person has his transgressions or sins forgiven--"having forgiven us all our transgressions." We also know that no one has their sins forgiven until they believe: "All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name" (Acts 10:43; NIV). Common sense dictates that since no one has their sins forgiven until they believe then no one is regenerated until they believe. But the Calvinists teach that regeneration precedes faith.
