Context

“This is what they get for living in their own righteousness, and not in the faith of the Son of God. The papists will tell you to do the best you can, and God will give you His grace. They have a rhyme for it: "God will no more require of man, Than of himself perform he can." This may hold true in ordinary civic life. But the papists apply it to the spiritual realm where a person can perform nothing but sin, because he is sold under sin. Our opponents go even further than that.” source
