Scotching the Snake of Pelagianism

'If anyone makes the assistance of grace [to believe the gospel] depend on the humility or obedience of man and does not agree that it is a gift of grace itself that we are obedient and humble, he contradicts the Apostle who says, "What have you that you did not receive?" {1Co 4:7}, and, "But by the grace of God I am what I am" {1Co 15:10}.'
