Irresistible grace (also called effectual grace, effectual calling, or efficacious grace) is a doctrine in Christian theology particularly associated with Calvinism, which teaches that the saving grace of God is effectually applied to those whom he has determined to save (the elect) and, in God's timing, overcomes their resistance to obeying the call of the gospel, bringing them to faith in Christ. It is to be distinguished from prevenient grace, particularly associated with Arminianism, which teaches that the offer of salvation through grace does not act irresistibly in a purely cause-effect, deterministic method, but rather in an influence-and-response fashion that can be both freely accepted and freely denied. The doctrine Some claim that fourth-century Church Father Augustine of Hippo taught that God grants those whom he chooses for salvation the gift of persevering grace, and that they could not conceivably fall away. This doctrine gave rise to the doctrine of irresistible grace (gratia irresistibilis), though the term was not used during Augustine's lifetime. According to Calvinism, those who obtain salvation do so, not by their own "free" will, but because of the sovereign grace of God. That is, men yield to grace, not finally because their consciences were more tender or their faith more tenacious than that of other men. Rather, the willingness and ability to do God's will are evidence of God's own faithfulness to save men from the power and the penalty of sin, and since man is dead in sin and a slave to it, he cannot decide or be wooed to follow after God: God must powerfully intervene by giving him life and irresistibly drawing the sinner to himself. In short, Calvinism argues that regeneration must precede faith. In contrast, Arminianism argues that God’s grace through Jesus Christ stirs up a willingness to know God and respond to the gospel before regeneration; it is how God intervenes that separates Calvinism from Arminianism. Calvin says of this intervention that "it is not violent, so as to compel men by external force; but still it is a powerful impulse of the Holy Spirit, which makes men willing who formerly were unwilling and reluctant." Despite the denial within Calvin and within the Calvinist confessions John Gill says that "this act of drawing is an act of power, yet not of force; God in drawing of unwilling, makes willing in the day of His power: He enlightens the understanding, bends
