The fact is this, no one has been deceived by Calvin, he merely expounded the truths of the Scriptures that Christ, the Prophets, Paul and others affirmed concerning the Sovereignty of God in all things, including election.
Another fact is many have been deceived by Robert Sandeman, Charles G. Finney, Andrew Fuller, and Pelagius and others who preach the false gospel of decisional regeneration and free will. Many on here have been hoodwinked by these and those of their ilk.
No one is free in their will; John 8:35, and salvation is not by choice; John 1:13; Romans 9:11ff, 1 Peter 1:1, 3, 5; James 1:18.
