Free Grace Versus Free Will by W E Best and published by Classics.
The same God who has ordained all events has ordained the free agency of man in the midst of the course of events He foreordained. The gospel is not forced on the elect against their wills (Ps. 110:3). Man has no ability to respond to God unless our wills are changed through regeneration by the Holy Spirit. God gives Christians faith to believe and obey. This change makes us willing to accept the gospel. Since salvation is entirely God’s sovereign and gracious act, it doesn’t depend on man, so it can’t be lost.
