If any man ascribes anything of salvation, even the very least thing, to the free will of man, he knows nothing of grace, and he has not learned Jesus Christ rightly. Martin Luther
Jim McClarty thinks through a few implications of the notion of free will.
Freewillism is that doctrine that says, “God loves you, Christ died for you, and the Holy Spirit is calling you; but it will all be vain unless you choose to be saved.” Freewillism makes the determining factor in salvation to be the will of man. It makes the work of the Triune God and the grace of God to be impotent without the consent of man’s “freewill.” Freewill religion is in direct opposition to the gospel of the free grace of God. The Bible declares that salvation is not accomplished, determined by, or dependent upon the will of man, but by the will of God (John 1:12-13; Rom. 9:16). The word “freewill”, when used with reference to salvation is a blasphemous obscenity! Don Fortner
