Robert Traill (The Throne of Grace), Works 1:165:
Grace helps in all the work and duty we are called to. Without assisting grace, the least piece of work cannot be rightly done, and by its help any work may be done: 2 Cor. 9:8, God is able to make all grace abound towards you; that ye always having all-sufficiency in all things, may abound to every good work. There is grace, all grace, and it abounding in God toward his people. From this given to them, there is sufficiency and all-sufficiency, and that always and in all things; and thence flows good work, every good work, and abounding to every good work. Like to this is his prayer, Heb. 13:20, 21, The God of peace make you perfect in every good work to do his will, working in you that which is well-pleasing in his sight, through Jesus Christ. We need grace’s help in every good work. No work is truly good, but what grace helps us to.
