If a plant grows with shallow roots, the storms of a season will wither away and uproot it; like a house built on sand, a poor foundation will doom its fate. But this isn't a book on botany, nor on architecture; foundations, good roots, are essential to thought structures as well as material structures. In theology, a bad foundation will produce results as catastrophic as bad roots or shifting sand. How we think about God and His work in the world will profoundly affect how we live and work out our Christian faith. This book evolved from the conviction that a prominent theological system rests on a fragile foundation. It is written as a small contribution towards refounding our understanding of God's relationship with the world and our salvation on His Word. The theology in question is Arminianism; the foundation is prevenient grace. Deep within Evangelical Arminianism lies the essential doctrine that God has acted in the life of all human beings, giving them enabling grace enough to respond or reject His offer of salvation. The contention of this book is that this doctrine has no biblical grounds and is rationally unfounded and that Arminianism itself stands or falls on this doctrine.
