How is the ability to respond in faith to the Gospel considered a work of man, when the Gospel itself is a powerful supernatural work of the Holy Spirit? It was and is inspired, carried and preserved by the Holy Spirit, right? Why does a work of the Holy Spirit have to be effectual for its results not to be called a "work of man?" Does the ability to reject the Gospel's appeal make it any less gracious? Does the ability to reject a gift make the Giver any less glorious for giving it? How does the ability to resist the work of the Holy Spirit in bringing us the Gospel appeal make it any less of a work of the Holy Spirit? Does it make those who receive it any less grateful?
