Not without the influence of the Holy Spirit, which is why he comments about the means of grace.From my reading of your quote from the Augsburg Confession and the theses from the Heidelberg Disputation of 1518; Luther pretty much was consistent in his belief that human will cannot effect a good work at all.
His comments are really against the Pelagianisn and semi-pelagianism he was taught at Erfurt.
Remember that the men He was referring toIn addition: Saint Paul wrote “ The spirit is willing, but the flesh is weak. “ which affirms that the human will, in accordance with common sense when you observe people in action; can will something good.
We’re living under His influence. Today His influence is by the Spirit and through the means of grace. Without these, the spirit is not willing, is incapable of being willing.
From the Ronan Confutation:
In the eighteenth article they confess the power of the Free Will - viz. that it has the power to work a civil righteousness, but that it has not, without the Holy Ghost, the virtue to work the righteousness of God. This confession is received and approved. For it thus becomes Catholics to pursue the middle way, so as not, with the Pelagians, to ascribe too much to the free will, nor, with the godless Manichaeans, to deny it all liberty; for both are not without fault.
