Even Arminians Believe that the Natual Man Has No Free Will
If the natural man has a free will to believe the gospel, then why does he need grace? If his will is naturally free then it would do away with the need for grace altogether. Therefore, anyone who acknowledges that even a LITTLE grace is necessary to believe, by default, acknowledges that man in his natural state has no moral ability to come to Christ. We all know that Jesus himself says (and I quote) "no one can come to Me unless God grants it" (John 6:65) and "the Spirit gives life (quickens) the flesh counts for nothing." (John 6:63). And Paul says "...no one can say “Jesus is Lord” except in the Holy Spirit." (1 Cor 12:3)
If you agree with the above statements from the Bible, then by definition, you already agree that man (left to himself) has no free will to come to Christ. You agree that his intentions are so sold to evil ... that his will and affections are under such bondage that he would never come apart from the grace of Christ. Therefore to teach that the natural man has a free will actually overthrows the gospel ... it is precisely because man is in bondage that he needs Christ to set him free." (John 8:34, 36)
So we have already ESTABLISHED that man has no free will. We all agree on this, EVEN ARMINIANS. The question really is what is the nature of God's grace? Is it effectual or does it merely help the sinner? Jesus answers this in John 6:63 when he declares: "All the the Father gives to me will come to me..."
